I think that the Wii's stellar time is going to pass soon. When its HD siblings bring into the market the new motion controllers (especially Sony's one, since it is what resembles more to the Wii model) the casual public will start to look at them.
At first it won't make a significant difference, I think, but it will impact sooner or later. Maybe the Wii catches up something at sales, but I don't think that it will last for a long time.
