I don't think Bond specifically needs Comic Con, I just feel that since Skyfall was released it's gained a completely new legion of Bond fans and I'm sorry, but if Comic Con where to confirm a SPECTRE panel, with Daniel Craig, Lea Sedeoux, Dave Butista, Barbara Broccoli and Sam Mendes then it would be something I'm sure everyone on here would be excited about. (Probably an exclusive trailer, with a Q&A and maybe a other major news scoop. (title artist, video game or something). I feel it's unfair to be in a mindset where SPECTRE is lowering it's standards by appearing at Comic Con because Bond is somehow 'too good for it'. At the end of the day, it would be great publicity and a very nice opportunity, especially for the fans that would go there from all parts of the world. It's a nice experience, and Comic Con is an exciting time for games, movies, comic books, tv shows. I don't feel it would be beneath Bond to get involved with that. They'll be finished shooting by July, It would be a perfect time to launch to publicity campaign over the summer.
I totally agree on that.
Plus, I do not have the feeling that Sony is positioning Bond as a "premium" franchise any longer. Marketing is definitely adequate to a blockbuster / first-class action movie (like let's say Avengers or Mission Impossible) and being at the comic con is the perfect place to reach the core audience
