Dark Knight Rises prediction: read if you want your mind blown.
Ok, since I saw the first teaser, one thing really stayed with me... the fact that Gordon is in the hospital, and being spoken to by Bruce Wayne (in his voice) who may also be in the hospital.
The name of the film is Dark Knight Rises. This clearly alludes to coming back from something. Bane is in this movie. Christopher Nolan likes realism.
Bane is going to break Batman/Bruce's back to start the film. This will end Bruce's tenure as Batman. However, Joseph Gordon-Levitt is playing a random cop about whom we know absolutely nothing... and that has to be on purpose.
My prediction is that the movie will result in JGL "rising" as a new Batman. I believe Nolan has even stated something like this will be the end of his "Batman Bruce Wayne story"... very careful statement there.
I'm sure I'm way off, but if this winds up true I want someone to remember I typed it up.
