So apparently to coincide with the new Justice League of America movie they're going to reboot the Batman series after The Dark Knight Rises, meaning new actor for batman and a new director as Nolan since he's is only producing. Personally I'm pretty disappointed with this because I really liked the realistic aspect that Nolan had going in his Batman series
