Gary Oldman has dropped some non specifics about the third Batman outing for Christopher Nolan. He hasn't yet read the script but he does know the story and says "it's great. It's a great, great story. You look at The Dark Knight and you think, y'know, 'How's he [Christopher Nolan] going to top it?' But I think he has."
Mr Oldman also hinted about the finality of the third film for Nolan and how the Rises brings it all back to Batman Begins. Whether or not this means thematically (as The Dark Knight shifted from Begins more comic book status to full on real world) or in story or spirit. Knowing Nolan it could very well be all three. Oldman also said "What Batman learns about himself at the end of this one will top off the trilogy."
We only have 15 more months to wait....
