As always is the case with trailers, this one was exciting especially because it was the very first one! The trailer is about 46 seconds and only shows some of the Naruto Shippuden: Ultimate Ninja Storm Generation playable characters that have been revealed. It shows one interesting thing, however - jutsu clashes! Well, just kidding. Timeskip and Pre-timeskip Naruto run at each other with a Rasengan, and it looks like they clash, but this could just be for this first teaser trailer.
Naruto Shippuden: Ultimate Ninja Storm Generation is in works for the Sony PlayStation 3 and Microsoft Xbox 360 by CyberConnect2. Currently, a release date for Japan, North America, or Europe has not been announced.
