Hmmm
PS3 did close to 12 million 2012 - Down around 2,3 million
Less than 10 million this year = 82 million
Less than 5 million 2014 = 87 million
Phased out in 2015/16 add another 5 million = 92 million
I would say it will stop around 90-95 million and not top Wii.
Predictions for 2009:
360: 39-42 PS3: 31-34 Wii: 67-70
Future projection
Wii will hit 100 million before christmas 2010 (made december 2008)
NDS Family will have sold and shipped more then PS2 at the end of 2009 (made january 2009)
