Call of Duty 4 answered 10 million times

Less than two months after Call of Duty 4: Modern Warfare officially reached the 9 million units sold milestone, developer Infinity Ward confirmed for News.com that sales of the military shooter were now in the eight-digit range. Arriving at a lofty sales figure almost as commonly reached by hardware platforms as hit games, Call of Duty 4 has sold 10 million copies worldwide.

Studio head Vince Zampella declined to break down sales by the game's various platforms (Xbox 360, PlayStation 3, PC, and DS), but he did say that the Xbox 360 edition had been the most successful to date. Zampella also explained the absence of a Wii version of the game.

"[I]t just doesn't fit on the Wii," Zampella said. "We thought it would be compromised to be on [that] platform."

Call of Duty 3 appeared on the Wii platform, but Infinity Ward was not the game's developer. Treyarch handled the Xbox 360, PS3, Xbox, and PlayStation 2 editions of the game, and Exakt assumed duties on the Wii version.
