I will be really PO'd if they go through all the work of putting 3D in this game even though only a handful of players will be able to use it, but then completely ignore the need of an offline multiplayer mode. I'm pretty sure that the reason Modern Warfare and Halo are so popular is because they're like the only shooters nowadays who bother to include a split screen mode.
