Re: Once Nolan's trilogy ends..
There's a big difference between Batman and Superman, though. Superman cannot be portrayed like Nolan's Batman. Superman flies, has super strength, can shoot lasers out of his eyes, etc. He is by nature unreal. I don't really think we can use Man of Steel to gauge how Nolan would handle being only EP on a Batman film.
