RedOctane has revealed Guitar Hero III will be coming to PS2, PS3, Xbox 360 and Wii on a release date in Fall 2007.
To quote RedOctane‘s support center Q&A: “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. — 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.”
Of course as soon as this slip up got leaked the quotes were removed, so thanks to Cubed3 and Kotaku for copying them.
