That's according to Wedbush Morgan's Michael Pachter, who suggested the game will sell 10 per cent more than previous title Black Ops.
Pachter also estimated that the Call of Duty Elite premium service could pull in up to 4 million subscribers by the end of the year.
As noted by our sister site Industrygamers, Call of Duty: Black Ops generated $650 million in its first five days, up from Modern Warfare 2's $550 million.
The highly anticipated sequel is due for release next week, November 8.
