Prolly not PS4 exclusive, though it should be. Stupid bastards made every other game in the series exclusive to one console at the time of release.

Well exclusive or not one console is cheaper and I have never had an interest in the Xbox(cept for when I've played Fable. I liked that).
All I know is Disney is buying everything and Square loves to play with the newer properties. Seeing Sora, Donald, and Goofy fighting alongside the Avengers would be just about the coolest thing ever. Same for a Yoda vs Mickey scenario.
KH doesn't work that way(though mixing all the new toys of Disney along with the old stuff into one big pile would be fun) but one could easily see a scenario where a FF Hero/Villain is on a noteworthy planet.
I mean Auron was brought back by Hades and he had the best lines in the game.
I have to say between Avengers or Star Wars, I'd be way more excited if KH3 mixed some Star wars in there. Avengers and Marvel are complicated and exposed enough as it is these days.
At first I thought that was a new Keyblade but apparently it's Master Eraqus'. That raises quite a few questions since the last person who had that was Aqua and she's sorta stuck in Hell the shadow realm.
The combat looks more KH2-ish but the movement(the jumping deftly on the wave of heartless and bouncing of a building like a ninja) is more akin to 3D's style of movement, which was really fun if a bit too flashy for my tastes(as in bright lights).
