In fact, Tornado hasn't even released in Japan yet. It was originally scheduled to come out last year, but later become delayed indefinitely. Oddly enough, though, GameFly has a listing for a DS game called Tornado. Can it be the same game? Perhaps -- we hope so, at least. We wouldn't mind having a portable Katamari-like game release in North America for our favorite handheld.
Whatever this game is, it's being published by Ignition Entertainment and has a GameFly release date of September '08.
