WHy does anyone care? Buy a game, pay for useless extras, or don't.
If the game is up to the standards of the "other" company's inbetween games, I won't pay a penny for it, if its up to Infinity ward type standards, I'll probably buy it for single player, and a few weeks fun on MP. I enjoy some MP but playing the same maps, for years on end holds literally zero interest to me, so paying extra to play the same game against the same people in the same maps with the same end result over and over again, not likely.
The game is either worth the price stand alone, or its not, any further cost for added stuff holds zero interest for me and won't effect if I get the game or not in the slightest.
I'm betting on them not hitting Infinity ward standards and making a POS game like black ops again, in which case I won't go near it. Infinity ward were losing their way with it anyway MW2 was a huge step backwards from MW1.
