But obviously their corrupted business models are working out

I trust Nolan very much so. I seriously doubt he'd make a sequel to this. He just isn't that type. Matter of fact, up until The Dark Knight, he'd never even made a sequel. I just don't think it's his style. And the Batman trilogy is different. He came into that knowing he was going to draw off comic book material and do a trilogy. Other than that though, all his original work has always been "nail it, then move on". I respect him as a filmmaker and I think he's just too original to dream of starting to pump out sequels all the time.

Yeah but when it comes down to business, he doesnt make the choice. Right now he is hot and a name everyone wants, so the studio wont be pushing him to do it. Its also WB and quality comes first for them, so thats another plus as to why this wont happen.

However Pixar had the same motive, but when the big boss man Disney stepped in and said "hey you do it or we will" then they go ahead and make something not of quality, it makes the film maker mad. Then they go "good you dont like it, if you dont want it released you make one yourself"

Well the good thing is (and the important thing to remember) is that the studios have said, they won't tread on Nolan in this instance. Nolan has expressed zero interest in a sequel to this film, and the studios have had the sense to say they wouldn't want a sequel without Nolan. That means they aren't just jumping the gun on it, but listening to the filmmaker. They know that without Nolan any sequel would fall flat.

Yeah its WB.

the only thing im worried about is that is right now. Nolan has several projects that ended after one now, like The Prestige, that could easily be developed into a slacker sequel for easy money. So I want to know when WB starts to hit a downhill slide, will they jump to extremes and milk these things.

I really don't think they will. WB wouldn't want to risk alienating their prize cow (Nolan). They could very well force him away and lose all that potential. That's why I feel WB will back off. As much as they want to, they understand that without Nolan any sequels to those projects would fall flat. They may want to, but they're smart enough to know that would be a mistake.
