GamePro reports that Ubi Soft has picked up the rights to this game and will release it in the U.S. It's already been released in Japan (a long time ago) and Europe (just recently). Anyway, if you are a fan of the first one, you should try it when it comes out. I liked it a lot. It's fun and very similar to the first one... the Karaoke boss is hilarious and the soccer mini-game is also fun.
