I'd be surprised if KHIII wasn't at E3. Square's been pretty forthcoming with the game recently, seeing as we got KHIII at E3, D23, and Jump Festa this past year.
It's a good thing you did. Who knows what would've happens if you hadn't stepped in. Probably something that Zack Snyder would find edgy.
It´s not that Zack Snyder likes being edgy, but that people are too damn kiddish. Yeah kh3 got cancelled, but at least we are getting a pachin.ko kh game.
