Personnaly , I said the 31st of December 2007 : "GTA IV : 13 millions, SSBB 12 millions ; Wii Fit : 11 millions "
So , I said like analysts ^^
I think it's possible : the install base in the end of 2008 will be around 44 millions for PS3-360.
13 millions would say on person of 3.5 will buy GTA IV, and I think it's possible
