With Wii Fit release in US and Europe, and some clever advertising in lifestyle magazines, i'm sure wii would sell 3 millions/month production trough whole 2008 (if there would be leftovers trough the year, it would be easily sold in the holiday time).
But i think 3,6 mil/month is pushing it a bit too much. Maybe in 2009 if it generates an even bigger momentum + most of 3rd parties start assigning AAA teams to work on wii games.
