Sales will go down, it's only natural as does many other consoles. But, it will go down only by lack of demand because the holidays have passed. I believe that there won't be much of a significant decrease in wii sales, especially since SSBB will be out in February. Mario Kart will also lend a helping hand, but I believe Nintendo will delay it's release for marketing reasons. By Christmas 2008 , demand will be a bit more tamed, and supply will meet demand by that time, and the wii will still be a hot buy. Nonetheless, I don't see wii flopping anytime soon
