guys, they don't say they took sales away, they say they took share away and this is true. black ops sold 26 million looking on vgc sales. bad company 2 sold 6.6 million. modern warfare 3 sold 27 million and battlefield 3 13 million.
so, the 2010 cod had ~80% share, the 2011 release has only ~67.5% marketshare
