for nintendo to get up to 100m wii's sold by december 2011, they have to start selling about 420,000 units weekly
to get up to 100m wii's sold by december 2012, they have to sell about 225,000 units weekly
if wiis hardware sales stay pretty close to constant they will reach 100m sales in about april of 2013
i dont think wii sales will stay constant, they'll continue their decline a bit after a new years sales increase. i doubt it'll get to 100m
