Some details have been leaked concerning the next "Guitar Hero" game. Gene Simmons of KISS will apparently be featured as a sort of emcee in the game; and Queen, Black Sabbath, and Metallica drummer Lars Ulrich will appear as recruitable characters for a new "quest mode". The game will lose the feature available in previous versions that lets you play songs from one band while using the avatar of another because Courtney Love sued over the feature. All songs from previous versions will also be available in the new one. A release date is not yet known.
