Wii Sports doesn't have a suicidal snowman's chance of surviving a car-crash in hell of beating 100 million.
Wii has sold 10 million this year. Wii Sports has sold 5.5 million. In Quarter 3 and 4, Wii Sports has sold 1.85 million while the Wii has sold over 5 million. The absolutely max attach rate you can expect Wii Sports to have with new machines is 50%. A more realistic number is 40%.
Wii Sports needs to sell 21 million. In other words, Wii needs to sell minimum 42 million more for Wii Sports to reach 100 million. Most likely, it'll have to sell more than 50 million more.
In other words, if you're predicting that Wii Sports will sell 100 million, you're predicting that the Wii will sell close to or over 140 million in total. That's just incredibly, incredibly, incredibly unlikely, with an incredibly unlikely cherry on top. It's just not going to happen.
