It'll never happen. Without a hard drive it's basically impossible. The song packs on 360 take 75 MB or more each. You'd be able to fit perhaps three on the Wii's puny flashdrive. Knowing this, Activision will never bother. That coupled by the fact that the douches at Activision have the nerve to charge $70 for a guitar shell (plus another $40 for the Wiimote) is why I'll be sending my Guitar Hero 3 package back to Activision for the $132. Screw them.
