Well, Activision is starting to talk up how big Modern Warfare 2 could actually be. In fact, according to Simon Wells, who is the brand manager for the Call of Duty franchise, it could be destined to be the “biggest selling video game of all time” when it is released before the holidays this year.

Activision recently announced that the last release, which was Call of Duty: World at War, is dominating play on the Xbox 360 and it has recaptured the crown as the most played title on the platform. The company also has reported that the recently released Map Pack 1 for World at War sold an impressive one million downloads during the first week of release.

Our sources tell us that Modern Warfare 2 is still on track for its November 10th release, and it is already expected to dominate sales this holiday season.
