If you are one of the people who were upset about the mono sound coming from your Guitar Hero 3 disc on the Wii, you’ll be glad to know that your replacement disc will be coming in February. That is, of course, assuming that you have already signed up on Activision’s GHIII Replacement Disc Pre-Registration website. If you haven’t, go do it now. As soon as the discs are ready, they will contact you and send you a prepaid return envelope with your copy of the game. As soon as they receive your game, they will send you the updated version.
