San Diego Comic-Con 2026 is almost here, and we already have some thoughts (and big dreams) for what is going to be announced this year.

After looking at the SDCC schedule and all the panels that are heading our way, the GamesRadar+ team has come together to create the ideal wishlist of all the movie and TV updates that we are hoping happen in some kind of way over the next few days. Below you'll find a round-up of some of the team's expert opinions, from potential trailers for upcoming Marvel movies to iconic horror adaptations.

Obviously, keep in mind that none of these have been confirmed just yet. We are hoping that they all do, but for now, they are just speculation. So, with all that out of the way, read on to discover what we think will be the hottest announcements at SDCC 2026, from upcoming movies to the newest TV shows.

San Diego Comic-Con 2026 wishlist

The Rings of Power season 3 casting news

(Image credit: Amazon Studios) The Rings of Power season 3 will be bringing Middle-earth back to San Diego this year ahead of new episodes in November. Showrunners J.D. Payne and Patrick McKay will be appearing alongside the cast as we expect more details about just how that time jump will impact the story.

However, we are most excited to see if it's finally revealed who Jamie Campbell Bower is playing. The Stranger Things star joined ahead of season 3 and has been having a lot of fun teasing fans about his connection to the Witch King. Our money is that he may be a little more Elven than audiences have realised though – could he be playing the long-awaited Celeborn? Only time will tell…

Blade Runner 2099 timeline details

(Image credit: Sony Pictures ) Prime Video has kept its long-gestating sequel series Blade Runner 2099 tightly under wraps since filming finished in December 2024. But with a full reveal just days away, it won't be long till we're all elegiacally muttering "I've seen things you people wouldn't believe…"

A first trailer, release date reveal, and plenty of insights from the cast (Michelle Yeoh, Hunter Schafer and Tom Burke star) are all practically guaranteed during the show's SDCC panel. But what we really want to know is how 2099 will connect to Ridley Scott's seminal Blade Runner and Denis Villeneuve's superlative sequel. Will Replicant-born children factor into the story? Given Blade Runner 2049's paradigm-shifting ending, it's the perfect avenue to explore.

A new Lanterns trailer

(Image credit: HBO Max) With the newfangled DCU stumbling slightly after Supergirl failed to soar at the box office, it's suddenly Lanterns' job to right the ship steered by DC Studios bosses James Gunn and Peter Safran. The elevator pitch – a True Detective-style mystery with a grizzled Green Lantern and a fresh-faced hero in training – holds plenty of promise, but the initial trailers showcasing Kyle Chandler's Hal Jordan and Aaron Pierre's John Stewart have lacked anything to make rivals Marvel Studios green with envy.

What we immediately want to see from its SDCC showing is a little more in the way of color and personality to help it stand out in a new trailer, as well as a slight taste from those attending on how it connects to the wider DCU. If nothing else, Lanterns ' panel needs to be a confident tone-setter for DC's next 12 months.

The Avengers: Doomsday trailer

(Image credit: Getty Images) Marvel could have its biggest year ever in 2026 with the release of Avengers: Doomsday , but, if it wants to have any hope of rivalling the shock announcement of Robert Downey Jr. as Doctor Doom at this year's SDCC panel, it needs to drop something huge. We are almost certain that means we'll get our first full Doomsday trailer, after one debuted behind closed doors at Cinema Con.

Plus, if Marvel wants to absolutely blow the roof off, it could also reveal more about its upcoming X-Men movie. Here's hoping we get a cast reveal, especially with rumors swirling that Adam Driver is set to play Magneto.

A Silo spin-off

(Image credit: Apple TV+) Silo season 4 is already confirmed, but we are greedy and hoping for news of a potential spin-off series during Apple TV's panel. Author of the Silo books, Hugh Howey, mentioned during a Reddit AMA that he has plans for another trilogy that follows Silo 40 "from before the events of WOOL to after DUST", so there is a chance here, folks.

We will say it is still a long shot, given that we've no word on these new books yet. But announcing whether we were going to get a spin-off and planting the seeds ahead of the show's final season would be a smart move and would also drum up excitement for Howey's new trilogy. It would be a win-win scenario, so we are keeping our fingers crossed.

A Carrie trailer

(Image credit: Prime Video) Horror legend Mike Flanagan is putting the boo in Ballroom 20, as the filmmaker makes his San Diego Comic-Con debut to tease his upcoming adaptation of Stephen King's beloved 1974 novel Carrie. The horror masterpiece has been adapted many times for film, but Flanagan's series, set to hit Prime Video just in time for Halloween, will explore the telekinetic teen's troubled time at high school over eight episodes.

Prime Video has already released first-look images and the official synopsis. Given how much information is already out there, we expect to see the first trailer at SDCC 2026. Deadline reports that the panel will include an "exclusive look at the series, behind-the-scenes insights, and a special announcement." Might we get a glimpse at the iconic prom scene? Or maybe King himself makes an appearance? However, we do know that Flanagan will be joined on stage by stars Summer Howell, Samantha Sloyan, Siena Agudong, Alison Thornton, Amber Midthunder and Matthew Lillard.

San Diego Comic-Con 2026 runs from July 22-26. For more, check out our list of upcoming Marvel movies and shows .

Someone has made a custom version of the Companion Cube case for the Steam Machine

This DIY effort is on Printables, and can be 3D-printed for those with the hardware and necessary skills

There are a growing number of custom projects around the Steam Machine, from faceplates through to full-on alternative takes on the gaming PC

Remember the ill-fated Companion Cube case for the Steam Machine? It had the plug pulled on it by Valve a few weeks ago, after maker Dbrand failed to get official permission to make its hard-shell case for the gaming PC, but now the concept has returned, in DIY form.

Tom's Hardware reports that a user on Printables, Jaron , has provided files that allow you to 3D-print your own version of the Dbrand Companion Cube (as flagged on X ). You can print the pieces, and a full set of assembly instructions (including smart video illustrations) and extra necessary parts (screws and so forth) are supplied.

As made clear on X, this is a fan-made creation implemented "from scratch" and it's based on images of Dbrand's Companion Cube. Whether it'll attract the attention of Dbrand's own lawyers, well, we'll just have to see, but you'd imagine that some leeway might be granted here given the situation and what happened with Valve.

The creator makes it clear that the case isn't an official product, is nothing to do with Valve, and that it doesn't use "any official assets from any game".

An additional caveat is that Jaron notes: "I have not done any extensive thermal tests but no airflow or venting is blocked, and the additional vent provided by the front face plate aperture logo can help provide a little extra airflow. So I don't believe there will be any cooling issues caused by this case."

My main concerns about the original Dbrand Companion Cube were bound up in cooling issues — especially on warm days, in confined spaces like a TV cabinet — and that remains true with this creation.

Still, if you were disappointed that Dbrand's case was cancelled, and you have a 3D printer and want to have a crack at making your own — and you're pretty decent with a soldering iron — you can now do just that.

Other Steam Machine companions

(Image credit: Goldboat90 on Reddit) Since the Steam Machine came out, there's inevitably been a lot of interest around the device, despite the high price . So, as well as this clone of the abandoned Companion Cube case, what else is out there in terms of Steam Machine customization?

New faceplates (front panels) are popular, and a much easier project than the above case, such as this example on Reddit (see the image above). I really like the slat effort here, and I can see why it's gone down very well with other Redditors (although I'm not so keen on the blue one).

(Image credit: PoisonISSweet666 on Reddit) What's also quite common is the number of custom small form-factor (SFF) PCs which are DIY takes on the Steam Machine , generally featuring beefier components (and at the same time, inevitably being larger than Valve's PC). 'The Orange Box' as shared on Reddit is a particularly smart example of one such effort with a strong Valve theme, built in a SilverStone SG05BB-Lite case. It has a Ryzen 7 5800X processor inside and an RX 9060 XT graphics card to give this considerably more pep than Valve's gaming PC.

There are other custom SFF PCs on Printables and this one from 3DCatt, which looks like a sized-up Steam Machine, has very similar aesthetics to fit your living room nicely, and a finished version someone has completed went very well indeed by all accounts.

Of course, there are issues around these alternatives to the Steam Machine as I explored in detail recently , and downsides to these custom SFF builds – albeit definite positives too, better performance being the main one. A PC that looks as good as The Orange Box doesn't hurt, either, and I'm sure we'll see more of these kind of SFF spins on the Steam Machine going forward.
