Whatever happens after the reboot in a couple of years will be interesting to see and what process Nolan follows as the Executive Producer of the thing...
EP could easily be a ceremonial title (for lack of better term).
After all, Burton and Spielberg were producers on, respectively, "Batman Forever" and the "Transformers" series but you don't see much of their vision in either.
I think once we see "Superman: Man of Steel" we'll have an idea how Nolan handles executive producer duties.
