VGC Poll: How many units will the Wii have sold by January 1, 2010?

[misterd]

minumum sales is 74.8m, given 46m at end of 2008, and manufacturing at 2.4m per month.

I'm guessing they ramp up production to 3m per month for the second half of the year, which would add roughly another 3m to that total, so I'll say 78m, give or take 1m.
