Back in March, Call of Duty 4: Modern Warfare already sold over 12 million copies after nearly 17 months on the market. Janco Partners' Mike Hickey is predicting that Modern Warfare 2 will sell over 11 million units in just 2 months and generate approximately $800 million at retail. “Given our CY09 sell through estimates for Modern Warfare 2, it’s possible that the game could be one of the largest entertainment releases of all time” The Xbox 360 and PS3 user base has doubled since the release of the original Modern Warfare. Hickey believes that the game can achieve that mark with the preorder campaign, and also hinted that the potential market for Modern Warfare 2 consists of a whopping 25 million gamers!
