“Mass Effect 3 sold more than twice as much as did Mass Effect 2 during its introductory month in January 2010,"
ME2 sold 572,100 in first month.
If true then ME3 seem overtracked. It also released on 3 platforms and had 4 weeks in NPD, while ME2 572k figure is for first week. Lets see how much more then twice it sold, maybe 1300k?
