Well, this is news. Several new Zygarde forms. It also shows a progression from the little blobby guy to dog form to normal Zygarde, to the new Titan form. The exact details on this haven't been translated yet, from what I know.
The new Greninja is apparently an alternate form, similar to cosplay Pikachu, rather than a Mega for a Gen VI Pokemon.
The anime is officially changing to Pokemon XY&Z.
I think this means that another new game is likely.
