I think its 1.66m after 3 weeks excluding Japan. Had it been released in November -December 2009 the sales would have been 2.5-2.8m after 3 weeks.
With Xbox exclusives or timed exclusives is a risky business these days. ME2 sold well but not what people would expect for a highly critically acclaimed game. Honest people will admit it. Metro 2033 sales are a joke. 360 version of FF13 sold better than anyone expected. Releasing a game on both consoles saved the sales otherwise we would have a flop like SO4.
