A lot of people used to claim GTA 4 was the reason that the Wii would not reach 50% this year. That's obviously not the case.
Right now, we're observing two things in the market:
(1) Sales of its competition (Xbox 360, PS3) are slowing
(2) Supply (and therefore sales) of the Wii is increasing
Wii Fit will increase demand for the Wii in the US over the long term. Right now, Wii Fit is sold out and is selling on ebay for $150-$180. It may be a while until my preorder with Target is finally filled.
The biggest question here is clearly Wii supply. Will the Wii supply increase to meet demand? Will Nintendo hit their goal of 2.4 million/month soon?
