Even before it was released, Gears of War 3 was breaking sales records. Over a million fans of the series had placed pre-orders for the game by May 2011, more than four months before its scheduled release date. As of 17 September 2011, Gears of War 3 had sold 1.3 million in its first week on sale, according to USA Today (http://www.usatoday.com/tech/gaming/story/2011-09-19/gears-of-war-3/50470880). But VGchartz.com gives a first-week sales figure of 3 million (http://www.vgchartz.com/article/88023/gears-of-war-3-sells-more-than-3m-copies-in-first-week/).
