Wii is only in the us really short on supply, in europe its usually no real problem to get a wii. So the question is mainly how many more wiis can nintendo sell per week in the us. I personally think 50-100k more each week should be no problem to sell for a longer period. with higher production numbers than that they will be able to get sales out of supply dependency ( at least outside the holiday season) which is probably exactly the thing that nintendo wants.
