I don't really see it happening, at least not soon. If anything, they'd make a game where you travel all the regions , as a last game when Pokemon's gotten the point where it's not making enough money or success. One problem I see if they released the game now or soon, is that there isn't really a handheld system that can hold enough apace for a game like that. Plus, whenever they make a new game/new generation of Pokemon, wouldn't they have to updated it? That be pretty tedious to have to do that and practically impossible.
