In my opinion Call of Duty is on its last legs. Call of duty black ops multilayer is just really bad.
Most of the PCgamers that I know play Battlefield bad company 2 over CoD:BO, its the closest thing we have to a modern Battlefield. Every one I know that plays PC Fps is hyped up about BF3, the possibility of another battlefield 2 with more solid game play and boom boom walls.
Will it pass CoD, I think no. Will it be better then Cod I say YES!
And for PC gamers I think its are next best shooter : D
Edit. Can every one stop saying your not going to beat Cod at its own game. CoD games and Battlefield games are Nothing alike. Battle field = mates working together in 1/2 groups, big maps, Armor and aircraft, team work. Call of duty = unlocks, small tight maps, Rambo 32/3 barging rights, unexplained boner at kill cam.
