Call of Duty 4 sells over 9 million copies

That's more copies than Halo 3 for those who aren't keeping count. Although part of it is due to it being released on three platforms (as opposed to one), it's still the best selling game compared to the other releases up until a year ago. Will be interesting to see how Grand Theft Auto IV fares.
