Janco Partners analyst Mike Hickey expect Infinity Ward’s shooter Modern Warfare 2 to sell a massive 11.1 million copies during its fist two months (!), that’s right 11.1 million.

A few months ago, Activision announced that the original Modern Warfare sold over 12 million copies in 17 months on the market. The analyst thinks the the sequel can beat that in a mere 2 months, because of Activision’s ramped up pre-order and marketing campaigns, plus the fact that Xbox 360 and PS3 install bases have doubled since the release of the original game.

No doubt Modern Warfare 2 will be a popular game, but we still find it highly optimistic for it to sell over 11 million copies in 2 months. Call of Duty: Modern Warfare 2 is slated for release on November 10 on PC, Xbox 360 and PS3.
