So much desperation for new Pokémon. I'd rather have a more grown up plot, a significant number of the player base are now over 20's. New games should be new story, balance changes, only occasionally new moves and new Pokémon who have actually had thought put into them.
So far half of the mega's are just for already good/popular pokemon (Blaziken, Lucario, Gyarados, Gengar, Mewtwo), I really want to see more Mega evolutions for pokemon like Kangaskahn and Mawile. IE making old pokemon viable/useful. Or even just taking less popular but beloved pokemon and giving them some special treatment.
