A scan from Shonen Jump shows Naruto Shippuden: Gekito Ninja Taisen SP. It's the sequel in the Gekito Ninja Taisen (Clash of Ninja) series. It's coming out December 2nd in Japan. Hopefully this game will get released in the U.S. for the Wii since PS3 and Xbox 360 owners will be getting Ultimate Ninja Storm 2 this October. If all else fails, there's always importing for the region free Wii!
