While supplies last (or through the end of the day), the discount is applied to the Wii, PS3, Xbox 360, and PS2 versions of the game. Guitar Hero 5 is worth investing in especially if you're loaded down with PS2 instruments and don't want to buy new ones for another console -- there won't be any more Guitar Heroes for PS2, after all. So, if you want more music, this is pretty much your last chance, all you PS2 holdouts!
