I think Famitsu made it clear they were waiting for a reaction and then were deciding what to do afterwards. However people REALLY need to stop blaming GameFreak when things come down to time constraints. It's not their decision to move the game, it's Nintendo. GameFreak can't really force their hand coz Nintendo is far too powerful. I'm sure now they're either going to try and patch things in over the next year or have all mons included in the follow-up game.
Corocoro is out so probably not I hope they'll start giving us "next trailer on this date" at the end of future direct
