At 35k/week it would be about 163 weeks.
At 50k/week it would be 114 weeks.
At 60k/week it would be 95 Weeks
At 75k/week it would be 76 Weeks
At 100k/week it would be 57 Weeks
To reach 10 million one year from now (52 weeks), it would have to sell 109,615 per week.
Those are some simple calculations. I'd say it sells between 60-75 thousand per week, so my bet will be 85 weeks based on my calculations. This is about a year and 3/4 so my guess will be:
September of 2009.
Edit: of course you have to take into consideration the possibility of a price drop, which will only increase sales.
