"A Massively Multiplayer Online Call of Duty?! Word on the street (according to IGN and other sources) is that mega-developer Activision is seriously considering such a venture.
With its recent acquisition of Blizzard, Activision thinks it may finally be in a place to enter the MMO market successfully, stating that past attempts have been failures in that they were financial losers or gained low profit margins.
So, as IGN puts it, would you play a CoD MMO?"
