Most of its audience already own it for GC or PS2 and many are aprehensive of the Wiimote controls and not aware of the ability to use the GC controller or PS2 control style with the traditional controller. So I think its a combination of factors working against it. It was smart to sell at lower price though. I am angry though that Europe and the "Other" regions are getting shafted on price though.
End of 2007 Predictions:
