The downside is that the areas based on international regions always feel too theme parky because the devs don't have an intuitive understanding of the region like they do with their homeland.
Personally I'd love to see a region based on Chubu (Cyan), and could even pull a Johto or Kanto post game. Or they could be absolute madlads and go after Tohoku, but they're not based enough for that.
