Guitar Hero 3 is coming to the Wii, Playstation 3 and Xbox 360 this fall, according to Red Octane.

The eagle eyes over at Cubed3 spotted the information in the site's knowledge base. Doing a little more digging I found a second reference. Unfortunately, neither are dated, so it's hard to tell how up to date the details are.

Here' they are, straight from the knowledge base:

When is Guitar Hero 2 (II) Coming? Will there be GH 2 for Wii, PS3, XBox, Xbox 360, etc?

Guitar Hero 3 for the Playstation 2, PS3, Xbox 360 and Wii are currently scheduled for release in the United States in Fall of 2007.

Will Any RedOctane Products Support XBox 360, Playstation 3, Wii?

Guitar Hero II from RedOctane currently supports PlayStation 2 and Xbox 360. Products for Sony Playstation 3 and Nintendo Wii will be out in Fall of 2007.

I have an email out to Red Octane to get to the bottom of this. Brian Crecente
