yeah i gotta think its overtracked, no offence to the guys who get the numbers.
Like come on, its having its best non holiday week ever during GTA4 week!
Even if it's an overtrack, it shouldn't be by too much given VGC's track record. It wouldn't be overtracked enough to make people stop thinking "why did Wii have it's best non-holiday week during GTA4 release."
This happened because Nintendo fired their big gun as well, only they two guns: MKWii and sending 400k Wiis to the americas for it's launch. Sony and MS don't have a second gun.
