How do we think Sun and Moon will be compatible with X and Y, if at all? Will we be able to trade Pokemon from those two games into XY?
I think as Pokebank and ORAS have shown, Gens could theoretically be a thing of the past now, because potentially EVERY game that comes out could have some new pokemon in it (like Mega Diancie, Mega Rayquaza, etc currently) so even if you caught a zigzagoon in Moon, you can still trade it to X Y or more importantly via Pokebank to that game as long as it has moves and abilities that exist in X and Y. (just like current pokemon are blocked or allowed to migrate freely to the other games based on the moves they know) so if the pokemon will be compatible with Pokebank, I don't see why they can't be traded to the other games provided their data exists in said game.
I don't know if Megas count as new Pokémon though...we might get Mega forms of Pokémon that were introduced in previous games, but if there's no new Pokémon (i.e. their own Dex entries) I don't think it'd count as a new gen, whereas a game that introduces a new set of Pokémon and a new regional dex would be considered a new gen, as it always has.
But I think we'll be able to move Pokémon from X&Y to Sun & Moon via the Pokémon Bank, but other than that it'll probably be a new gen like any other--not much compatibility other than the ability to transfer from the older to the newer gen.
