Well developers know that a games lifespan is in its online multiplayer. Why shouldn't they focus on that? Just look at the Left 4 Dead games - they essentially have no single player campaigns.
Hmmm while that is true, I Think also single player promotes the form of story telling other than games. Really anyone can make a multi-player game filled with everything. Though part of the multi-player is still reliant on a bit of story telling. Backgrounds of characters, why you are fighting etc. Plus, some people (I prefer) like a good video game story. I didn't play halo for the multi-player, I played it for the story and the Universe. I got Call of duty games (not black ops... yet) for the story, it seemed interesting and unique story telling.
