The guitar-fueled rock-fest that took many gamers by storm last November have a lot more face-melting to do over the next two years. RedOctane CEO Kelly Sumner says that we will likely see five or six new titles in the series by the middle of 2007.

Guitar Hero 2 is definitely in the works with over 40 new tracks, while Sumner hints that genre-specific editions like Country and Western or Metal were also a possibility.
