It probably sold less, actually.
We have the first 6 Weeks overtracked for the game. EA said they sold 1.6 Million units on 360 and PC combined (including DD sales) by the end of March 2010. Links here, and here.
360 sales for the first 6 Weeks are currently sitting at 1,447,548
PC EMEAA Retail Sales for the first 6 Weeks are at like 75,000
Add them together and you get 1.52 Million.
Considering that the game sold much better in America than it did in EMEAA, and that DD sales aren't even counted in those PC numbers, I think it's safe to say it's still overtracked, despite a recent downwards adjustment on the 360 version. Probably by another 150-200k...
Would also like to say that Dante's Inferno, FIFA and Battlefield data all matches up to what was said by EA.
