Remember, "all of these within the next 3 years" is something entirely different than "all of these in 3 years". My bets are still on 2018 for KH3 (for Japan at least), it's almost definitely further along than FF7 Remake and the new Marvel game.

I feel like the jump to HD and then the development hell of 15 just completely screwed all of their plans and schedules, so with those two out of the way things should speed up at least a little again.
