I've been wonder where the Pokemon BW will take place, and which region of Japan they'll base it on. We know that Kanto is based on the Tokyo area, Johto is based on the Kansai region, Hoenn is Kyushu at a 90 degree angle, and Sinnoh on Hokkaido (plus the southern half of Sahkalin island, which was Japanese territory from 1905ish to 1945, and the disputed Kurills). My money's on Shikoku, which is the only island they haven't used yet.
