Activision (ATVI +1.3%) warns (tweet) that its Call of Duty: Modern Warfare 3 is selling so fast the company's servers are having trouble registering new players - creating a "bottleneck" for its new Elite section of the game. Wedbush's Michael Pachter says if the company keeps its marketing edge in place - the game will be the best seller of all time.
