A new Naruto Shippuden 3DS scan from Shonen Jump magazine has been released! It shows Naruto using Rasenshuriken, Giant Rasengan, and an in-game transformation to Sage Naruto (thanks to hokagesdaughter for pointing that out in the comments).
Naruto Shippuden 3DS is a side-scrolling adventure with 3D image projections. Thus far Naruto is the only confirmed playable character, although Sai, Sakura, Shikamaru, Kakashi, Sasuke, and the Five Kages will be in the game. The game is slated to be released by Takara Tomy on March 31, 2011 in Japan. There is no word on a North American release at this time.
