Well it's hard to say.
Because I do think there will be months where the Wii will not have the highest sales WW, but I think that will be short lived i.e it's only in the #2 spot for 1 month, no more than 2. And I do think there will be a lot of months like that. Maybe not this year, but possibly sometime later next year, Christmas perhaps?
Now if we were trying to figure out when the Wii will stop winning combined monthly sales... I'll say sometime late 09, I don't wanna say never, because I think by then most people who will want one will already have one and 360/ps3 should have price cuts by then. But I don't think there's a doubt in many people's mind that the Wii will pretty much win the "war" lol.
Wii60 owns and that's all anyone needs
