Rock! According to IGN, Guitar Hero 3 on the Wii will soon be in ear-blistering stereophonic sound. The game was originally released with only mono sound options, which was less than ideal if you wanted to, for example, rock and roll all night or paint several things black. Activision, bless their leather pants, will have free replacement discs available for all in early 2008 which will contain the full, rock-tacular stereo and Dolby Pro Logic II options. Rock!
