@GameReviewGuru It actually does make sense, because the regions in Gen 1-4 were all based on a area of Japan. The Unova region in Gen 5 is based on the area of New York. This would make sense if they were all putting it into a map of Japan. Also, they only said that the settings would be from Gen 1-4, so they won't be removing the Gen 5 pokemon if this is true.
