"Call of Duty: Modern Warfare 2 has exceeded our expectations and shattered theatrical box office and video game records," said Acvitision Blizzard CEO Bobby Kotick. "There are only a handful of entertainment properties that have ever reached the $1 billion mark, which illustrates the power of the Call of Duty franchise and mass appeal of this game."
Activision has previously boasted that MW2's PC, Xbox 360 and PlayStation 3 release on November 10, 2009 was "the biggest launch in history across all forms of entertainment" with estimated sales of $550 million US in the first five days alone.
Multiple downloadable content packs are expected this spring. Rumour suggests that Infinity Ward's next project after MW2 will be some manner of MMO, while other whispers hint that a third developer will be brought into the Call of Duty fold.
