In the previous Guitar Hero (3) for Wii, it was listed in the manual as used for "expansions", none of which exist right now. Nobody knows what it will be used for, if ever, and CURRENTLY HAS NO USE. It was not used at all in the previous Guitar Hero title and it is unlikely it will be used here, too.
