Activision is planning to innovate the Guitar Hero franchise. In a conference call yesterday, Publishing CEO Mike Griffith said, "For the holiday, we will provide a significant leap forward in innovation for Guitar Hero worldwide, on all platforms." That includes PlayStation 3, PS2, Xbox 360, Wii and DS. Griffith also said that more information will be provided "in the coming weeks."

We wonder if this has anything to do with those recent rumors about Guitar Hero IV going multi-instrumental. Guess we'll find out soon.
