Probably sold pretty badly and it looks like it deserved it. I'm not saying Call of Duty deserves 20m+ sales a year, but at least the biggest gaming audience is still somewhat discerning about quality.
I played MoH 2010 and it was dire. EA should forget about this genre and do something else. They have no hope of making a dent in Call of Duty's mind share after the last few after the last few half-arsed attempts they've made.
