I don't have GH3 yet, but I was wondering if anyone knows if it will be possible to get an extra guitar controller. Or does multiplayer mode work in online only?
from the research I've done, it appears there are no individual guitars being sold for Wii yet. However there will be eventually, but probably later rather than sooner.
The thing that sucks is, because the wii version uses the wiimote for much of the expensive parts, an extra guitar probably will be a different price than extras for 360, so theres no way of knowing how much cheaper it will be than the cost of the game+guitar.
