Joystiq is reporting that Red Octane is considering three new sequels to the uber-popular Guitar Hero franchise and they have the logos to prove it.

Their source tells them that Guitar Hero: World Tour, Guitar Hero: Encore and Guitar Hero Axe Grinder are all under consideration. Hit Joy for a list of some of the other names under consideration. I just hope that Red Octane is also thinking about expanding the game to include more than just new songs with every iteration. Come on Bass. Brian Crecente
