Naruto Shippuden: Ultimate Ninja Storm Generation was first outed by Famitsu earlier this month. Here's the first trailer of the game in action. It's of pretty poor quality, but we aren't complaining when Haku and Zabuza are kicking ass.
Developed by CyberConnect2, Ultimate Ninja Storm Generation will bring the two time periods of the Naruto manga/anime together. Pit young Naruto against Shippuden Naruto, Haku against Bee and Zabuza against the Raikage!
Namco Bandai have yet to formally announce the new Naruto title, but with the trailer leaked, you can expect the announcement to come pretty soon. If Storm 2 was any indication, Generation will likely be on both PS3 and Xbox 360.
