I was literally yelling at Nomura when he said "one more trailer". I was like, "Don't lie to me, you bastard! Don't you dare do it!!" Once the Disney logo showed, it was pretty much a lock and I was thrilled.
If you're on this board, it's probably safe to assume the KH3 announcement hit you like an invisible sledgehammer. I'm personally ecstatic and can't wait to hear more (hopefully before the PS5 comes out, Nomura). But there's always one topic that needs to be on a KH board and that's one where we postulate about what Disney (or Non-Disney) Worlds, characters and homages we'd like to see.
Personally, I think Pixar Worlds need their due. A Sora action figure in Andy's House (Toy Story), Sora, Donald, and Goofy in masks and capes (The Incredibles), Or a second under the sea experience at the Great Barrier Reef (Finding Nemo). Maybe Pixar hasn't been hitting homers recently but they've still got more hits than misses and I think skipping out on these worlds would be almost criminal.
Outside of Pixar, an obvious conclusion that I've been mulling over for a while was Game Central Station (Wreck-it Ralph). The meta humor pretty much writes itself. Does Ralph recognize Sora as a famous video game character? Will the Kingdom Hearts "game" be in danger of an unplugging at some point? Is there even a Kingdom Hearts "game"? That'd be pretty sweet.
Also just a toss out to SE, despite my dislike of the game itself, I'd actually love to see Lightning make some sort of appearance. Well probably see but this dual announcement makes me think Noctis will make an appearance too.
