During Microsoft's Xbox E3 press conference, Square Enix showed off a brand new trailer for Kingdom Hearts III, which appears to feature a whole lot of characters from the movie Frozen. We also saw many from Tangled, Monsters Inc., Toy Story, Hercules, and Mickey Mouse.
An interesting feature we noted was that you can seemingly blend in to these Disney worlds like a chameleon. This had combat and world traversal capabilities.
In other news, Square Enix announced a January 2019 release for the latest entry in the Kingdom Hearts franchise just this morning.
