Not much. Wii U will be out when Wii hits $99. So I guess it will sell about as well as PS2 did when it hit $99. Or maybe Nintendo will stop production of the Wii before it hits $99. It all depends on what effect Wii U has on Wii Sales. If Wii U launches at a relatively low price for a new console then I can see Wii sales dropping off precipitously and putting a $99 price tag on it won't do much if anything.
I don't see Wii having the intergenerational legs of PS2. After all, it's only 3rd world countries where PS2 is selling appreciable amounts and PS2 is outselling Wii in those countries almost 2:1. So Wii doesn't really have a dominant presence in markets that can sustain Wii sales for years after Wii U launches.
