Update: You won't find any new Kingdom Hearts III gameplay footage, but Disney's Roy Conli appears in a new video to explain some of the reasoning behind Big Hero 6's inclusion in the game.

Regarding the Big Hero 6 timeline and where Kingdom Hearts III will overlap with it, Conli says it takes place after the events of the film where the team has already been formed. Conli also says that Baymax will appear (as if there was any concern that he wouldn't).

Original story: Get ready to explore San Fransokyo in Kingdom Hearts III.

Announced during Disney's D23 expo, which has been home to a number of news details related to Star Wars and upcoming Pixar and Disney films, Disney confirmed that Big Hero 6 will feature in Kingdom Hearts III as a dedicated world.

Our Take

Big Hero 6 is a perfect addition for Kingdom Hearts. Its setting, San Fransokyo, was a very cool aspect of the film that didn't get a whole lot of exploration outside of a some establishing opening shots. I look forward to spending time in the city.
