Well, I guess there is a possibility that the new games could be set outside of the Japanese region. Geographically at least, the Pokemon world is kind of a parallel to our own, except all the animals are Pokemon. We also have Lt. Surge, confirmed as an American in the games, and Fantina, who is from a French-speaking nation. So if the developers start running out of Japanese regions to emulate, they're gonna eventually have to go elsewhere.
