Booh! on 01 October 2011
I cast some doubts on those numbers. Major Nelson said "[Gears] sold more than three million copies in its first week since release"(September 29th 2011), that is seven days after its release (September 27th) it has sold more than 3 millions. Thus or it is overtracked or the first days of the second week were underwhelming (otherwise he could have said 3.5 millions or something like that).
