Nintendo attracting NEW people to the market is not the same has existing gamers (150 million of them) wanting something different. In fact it's just proof that Nintendo needs new consumers for the Wii to be a success. Everyone here should remember that the Cube was very strong out of the gate too. They sold about 75% as many Cubes at $300 that they have Wii's at $250 w/free game in the first 3 months.
I think that Nintendo WILL bring new consumers into the market and the will be successful with Wii, but I don't think it's even possible that they will dominate.
Cube sold for $200.
And by the way they sold 4million GC's in Japan to date. 1.2million Wii's so far, 2 months in.
