>>28071995Look at it this way; the anime exists to hype and sell the games. Now there have been anime exclusive conceits before, but never anything as central to the story as Greninjash was.
We'll definitely get at the least an event Greninja on it, and I'd be surprised if synchro/bond phenomenon/whatever doesn't make an appearance in Sun/Moon in some shape or form either.
The only thing that really seems a little shaky is that they made the new big gimmick in synchro lose to last seasons new gimmick, Megazard.
