This rumor has been proven false. The demo coming in August is for Naruto Shippuden: Ultimate Ninja Impact. Please see the scan here.
We’ve seen a handful of gameplay videos from Japan Expo featuring the Raikage, Sasuke, timeskip and pre-timeskip Naruto. That must mean there is a demo, right? Well, rumor has it Japan will be getting a Naruto Shippuden: Ultimate Ninja Storm Generations demo this August! The news will be featured in the up-coming issue of Shonen Jump magazine. We can’t recall Microsoft’s polices off the top of our head for 360, but unless Sony has changed their region-free capabilities recently, PlayStation 3 users worldwide will be able to download the demo if they have a Japanese PlayStation Network account. It’s possible Namco Bandai and CyberConnect2 will release the demo in North America and Europe around the same time so no fan is left behind, but that’s just our hope so it may not happen. We hope to have more information more on the demo as it breaks.
Naruto Shippuden: Ultimate Ninja Storm Generations is a 3D fighter in works by CyberConnect2 for the Sony PlayStation 3 and Microsoft Xbox 360. It is scheduled to be published in North America, Europe, and Japan by Namco Bandai Games in 2012. For more information, please visit the Naruto Shippuden: Ultimate Ninja Storm Generations section.
