There hyping the graphics to be as best as they can be, nothing has been said about the game itself, in my eyes the campaign makes a game what it is, no matter how realistic the graphics are.
But Battlefield has never been a game to focus on campaign gameplay though, I mean BF didn't even have a legit campaign until Bad Company 1 came around and it BLEW! Battlefield has always been about the online and will continue to be. I just hope BF3 has a good campaign, like they're hyping it up to be.
