Square Enix treated us to a surprise first look at Kingdom Hearts 4 this past weekend, and while we still don't know anything about a potential release date or platforms (no word if it'll be on Xbox yet), fans already appear to have spotted a reference to Star Wars in the trailer, and it's easily missed if you don't know what you're looking for.

The bit to focus on is at 0:34 in the video above — in the top right corner, you can see what appears to be the foot of an AT-ST walker, in an environment that looks very similar to Endor from Star Wars Episode VI: Return of the Jedi.

In a press release, Square Enix confirmed over the weekend that Kingdom Hearts 4 is currently in "early development" and will introduce "an epic new storyline titled the 'Lost Master Arc'." Here are a few more official details:

"Beginning with Sora facing off in a boss battle against a giant enemy, players are introduced to the Quadratum, a large, expansive city set in a gorgeous, realistic world unlike anything ever seen before in the KINGDOM HEARTS series. Fans will be excited to see the return of Sora’s well-known companions Donald and Goofy, in addition to the first appearance of Strelitzia, a mysterious new character who appears before Sora in this strange new setting."

Fingers crossed this Star Wars crossover turns out to be true, and here's hoping KH4 actually launches on Xbox as well!
