Pokémon X and Pokémon Y

I wouldn't be surprised. Hell, we already have one: MegaBlaziken, already confimed to only be available during the event.

I don't think wifi events and dlc things are quite the same thing. Presumably the blaziken megastone event is just going to be a wondercard equivilant like 4th/5th gen, and everything is already on the game card for mega blaziken.

Nintendo will probably start charging for pokemon dlc soon though, given it's become blatantly obvious people will pay for them. (Did anyone really buy pokemon radar for the "game"?)
