Balance > Realism. No attachment (in theory) should make a gun superior, and the accuracy decrease was designed to uphold that.
Of course, then the GL came into play and we lost all sense of balance, but that was the intention.
As for co-op, they won't be having a campaign cooperative mode, but instead they'll be doing what's called the "Special Forces mode." Basically, it takes all the awesome level ideas that IW couldn't fit into the story and allows you to play them seperately with a friend. They say the levels are in the spirit of Mile High Club from CoD4, which has me sold already.
