Patapon 3 still doesn’t have a release date at this point after the delayed announcement, but they are expecting sometimes early next year. However, a new demo is releasing in Japan on January 06, 2011.
The new demo will incorporate the feedback Pyramid and Japan Studio got from the first demo and will be around 100 hours long. It will also have 9 featured characters to let you choose from single-player and multiplayer mode.
Patapon 3 was originally scheduled for 2010 release, but it has been delayed to next year for developed reasons.
