Call Of Duty: Black Ops Is A Big Deal. Even On PlayStation 3.

While the publisher was keen to point out its achievement, no hard figures were actually given. Assuming the publisher's correct, Black Ops will have outsold Gran Turismo 5 (6.37 million copies) to take the top spot.

The numbers would have been nice, but it's not exactly a stretch to lend credence to Activision's claim. Call Of Duty is pretty popular after all.
