DSi launch title: Rhythm Heaven dated April 5

Nintendo has the perfect companion piece for that DSi you'll probably end up buying on April 5: Rhythm Heaven! Coincidentally, Rhythm Heaven will also be the best way to console yourself if you walk into a store and find DSi systems sold out. In either case, the rhythm microgame collection from the WarioWare team will be available in North America on April 5, exactly as "predicted" by retailers, and is compatible with all DS hardware models.

Nintendo is seemingly putting a lot of confidence in a very strange game by positioning it as the DSi's "launch title." This is an especially surprising move considering that Nintendo never released the Game Boy Advance predecessor, Rhythm Tengoku, in North America, despite its hit status in Japan.
