Kingdom Hearts IV: Star Wars Crossover indicated in the trailer

Yesterday Square Enix Kingdom revealed Hearts IV with a first trailer and confirmed the early development of the game, which follows the “Lost Master Arc”.

At the beginning of the trailer, a forest flooded by light is shown with a small waterfall.
In one of these short scenes, there is something to see on the upper right’s edge of the screen, many of which believe it would be a foot of an AT-ST.
At-St’s are two-legged rectangles endor on the Waldmond Endor in Star Wars: the return of the Jedi Knights took up the furry Ewoks in their plush courses.
Good possible that endor becomes a playable scene in Kingdom Hearts IV.
