Cmon man - I know you are smarter than this!
Noone went into TDK thinking Batman could die, because
1. Noone went into it truly expecting it to be Nolan/Bales final Batman film
2. It was not marketed as the 'epic conclusion' or the end of Nolan's Batman trilogy.
3. Not as important a point as 1 or 2, but still. Bane.
Also, regarding your earlier point about Nolan's films being standalone. I agree that thus far that has been his approach. But if you read his interviews and cast interviews, whatever little they have revealed about TDKR so far all seems to indicate that this is NOT a standalone film, it is the conclusion to a body of work. The film
'goes back full circle' to Begins according to Oldman and Wally. While Nolan adds that the film starts 8 yrs post TDK because they wanted to give the
events at the end of TDK 'gravity' and 'space' to have context and meaning. Bruce Wayne has been frozen in time for 8 years, he's still grieving.
I'd argue TDKR is certainly not meant to be a standalone piece.
That's the only point i've been trying to make.
Regarding expecting Batman to die in TDK.. see above. Misses the point.
I also happen to believe we will see Batman live, and that we'll see a deep character study of Wayne/Batman, which possibly leads to the conclusion that Wayne does not exist anymore. It's just the Batman. But i'll be going in with an open mind to the possibility of him dying despite believing that he's likely to live
Now that may change depending on what is revealed to us by trailers and any further interviews, but I suspect they deliberately want the audience to feel the true danger and threat in this one, so i'm not expecting the trailers to give us anything on the ending
