There are a few mixed messages out there today about how compatible Pokemon Alpha Sapphire and Pokemon Omega Ruby will be with Pokemon X and Y. As it turns out, there WILL be SOME compatibility between the lot, but not a massive amount. Neither Primal evolutions nor Mega evolutions will be available in X or Y. You might be able to fight them, but you won’t be able to use them in X or Y - or so we were told in a tip. But it’s not that simple.
