Pokémon X and Pokémon Y

So this thread is like 91 pages long and as much as I'd love to go through it entirely and catch up on everything I know that'd take way too long

Is there a definitive list of all the differences between Pokemon X and Y anywhere yet? I'm still not sure which version to get, so if there are certain evolutions only present in one game, or some Pokemon as X/Y exclusives I'd like to know beforehand so I buy the right game.

..I'll probably end up getting whichever version I don't get later anyway, but ;_;
