Look, all the stuff that's been changed since gen 3 was changed for a reason, and with X and Y being such huge steps forward, it'd really be a shame to see Game Freak working backwards for "Nostalgia." I understand for many people this was their first Pokemon game, but Game Freak has FINALLY decided to start taking risks and going forward, let's not ruin that so soon, or we won't see any major changes for another decade at least.
