I expect it to be less than any previous COD title...The game is missing the campaign which will impact some of its sales. Not only that, but with an eliminated campaign, you are getting the normal count of maps like previous years.. which is a complete rip off. Blackout mode is just another one big map which i think will get boring after a few days of playing. We should have got at least 16 maps as part of game release to make up for the missing campaign..
Activation is a such a greedy company, they saved all cost of building a campaign (development, story narrative, voice actors) and still delivered the same number of maps in MP. People should not allow this to happen, speak with your wallets and don's buy the game.
