It's kind of strange that Zygarde still has access to Aura Break. Great way to screw people out of using Zygarde-Complete, which is made worse because Aura Break is completely useless.
You *could* use an Ability Capsule, but unless its cost is reduced, that would be a pain.
I'd wager on 1) more than 2); there's still some time left for Generation VI (if nothing else they haven't officially revealed Volcanion yet).
Also looking at it some more I'm definitely getting a Zygarde vibe from the ~mystery Pokemon~.
Mega Charizard Y confirms Mega Evolution, though I'm still not sure how that would be done. (Maybe like Burst attacks in Etrian Mystery Dungeon, or Mega Evolutions in Rumble World?)
Also, given that there's evolved starters on the box art...does that mean we'll finally be able to evolve before...
