I don't even see the Wii hitting 100 million. Sales will eventually drop off and third parties are too lazy to put out quality games on the level of Nintendo devloped games.
If and/or when the Wii gets PS2 type support, the 100m barrier might be broken.
It'll still be the highest selling console this gen though.
