It seems like Mystery Dungeon is the Pokemon game this Holiday. Z/X2/Y2/whatever will come next year, to coincide with the 20th anniversary. Just my guess, Game Freak could surprise me.
There will be at least one N3DS exclusive, no telling what it might be. With Fire Emblem, Bravely Second, and Yokai Watch all coming next year, I do wonder what Nintendo has planned for this Holiday in the West. They must have a game, because none of the other potential localizations are really big enough to lead the charge come Nov/Dec.
*shrug* maybe it's just Pokemon, after all.
