If sales started to slow for wii, nintendo are in the strongest position to offer a price cut. I'd be surprised if sales didn't stay very strong until at least 2010.
It's still sold out at most shops... that demand's not going to evaporte in six months, especially as the games available are really set to get stronger.
The wii's price advantage isn't going to disappear either. By the end of this generation, I think nintendo will have been able to lower the price to the point where even those with almost no interest in a wii will have picked one up for the exclusive content.
