I heard Kindgom Hearts 3 is confirmed to be a multiplat coming to XboxOne as well. Base on the history between Nintendo and Square-Enix, its ...possible.Not sure about FF15 ,but I have a better feeling KH3 could come to the platform, depending how well Nintendo market the Wii U who's knows even FF15 could make an appearences to. PS. Sora for Smash bros. :3
