Is it ok if I say Pokemon X & Y doesn't impress me at all? Using 3D and adding more pokemon doesn't somehow enhance the incredibly dated battle mechanic.
but they did add stuff to the battle mechanic... mega evolution, triple battles, rotation battles. also just the online features (which are only possible because of the 3ds) alone that they added is enough to warrant the purchase imo.
btw pertaining to the "dated battle mechanic". Why fix what isn't broken? It's been proven to work over atleast a dozen entries in the series, why risk changing it and it possibly be shit? I personally don't think there is anything wrong with the core battle mechanics.
