I don't think the goal for Nolan or WB/Paramount is for this film to make a billion dollars. And it won't. In fact, the co-distribution sort of confirms that neither company will lose much money, because they're both going in 50/50.
So, the goal of this film is to be an art film, and the November release date gives it the Oscar push because it's in Awards Season. This isn't trying to be The Dark Knight Rises or The Avengers - it's trying to be the Oscar buzz film. It's an entirely different animal. So, box office numbers will probably be low, and it's expected.
But the issue of whether or not it will make Dark Knight/Inception/Dark Knight Rises numbers is irrelevant. I wouldn't be surprised if it's on par with Batman Begins and The Prestige. The goal appears to be getting Nolan out of the "comic book funk" that he's in and establish him as a REAL filmmaker who should be taken seriously, especially at the Oscars. Now, whether or not Nolan actually cares about this, who knows. I doubt he does. But I bet WB/Paramount cares VERY much.
I mean, don't forget, these two competing companies came together for this one movie. That's not a common thing. There are suits on both sides of the line who know that it's something special. That alone indicates that this has a serious - I mean serious - chance of sweeping the Oscars.
