If they do announce this year or early next I think the release date will be a little after the American release date of Pokemon Mystery Dungeon: Magnagate and the Infinite Labyrinth
They kinda did the same thing in that pokemon BW2 was released a couple of days after the American release of pokemon conquest. Now I'm not saying this is some sort of pattern I'm just taking a guess here.
Also anyone think that localization time will be cut down for future gens?
Heck if its a remake we are getting I think the localization should be even shorter than it was for BW2 I'm Hoping for no more than a month
