Scratch the rumor about Patapon coming to North America. Sony confirmed they will release the unique rhythm game in February 2008. The turnaround is pretty quick too. Patapon makes a world debut on December 20th when PSP owners in Japan can pick it up. Two months later the drums of war beat in North America.
Not sure what Patapon is? I spent some time with Patapon and wrote up impressions of how you control the tribe with drum beats.
