Nah, that was a joker on twitter who said that. He also said a man in a Batman suit wanted to give Nolan a BJ and that McC was encouraging them! That tweet got re-tweeted about 1000X before the guy admitted he hadn't gone to ComicCon and was just joking.
Nolan made 3 batman films, revolutionised comicbook filmmaking forever, and never made a visit to Comic-Con. Now, suddenly a new trailer (with no new Zimmer music attached) and an appearance at Comic-Con a few months before premiere. Anyone else sensing a "push" from the producers (need for extra marketing, too much secrecy etc)?
