Since this generation has relatively few "new" event things to extend its lifespan with (just the three legends and Mega Lati@s), what other events do you think we'll get down the road?

There'll undoubtedly be a Pikachu of some kind, probably an Arceus, and perhaps a new Mew giveaway to go with the fact that Mewtwo is in X/Y.

There were some Plasma event Pokémon in Gen V (Deoxys and Genesect) - think we'll see some "Flare" event Pokémon this time around?

Come and speculate!
