OK so new information this week.
First Nintendo lowered estimates for shipments through March 31st 2011 from 17.5M to 16M (had previously lowered from 18M to 17.5M).
Second adjustments occurred on the site and for the time period the OP poster is talking about in 2010 the Wii sold
18,563,777
Third weekly numbers came out for this week and Wii was down 37% YoY.
The Wii is now 634,190 behind last years pace which ended at 18,563,777.
OP predicted Wii to sell 22.1M through December 24th 2011 (52 weeks starting December 26th 2010). If Wii stopped declining and acted exactly like 2010 the rest of the way the total would be 17,929,587. So to hit the 22.1M the Wii needs to sell 4.2M more the remainder of the year compared to last year. That is roughly an 87,000 weekly increase over last year when so far this year Wii is averaging a 158K weekly decrease compared to last year.
Its libraries that sell systems not a single game.
