Some quotes that came to my mind, when I think of Batman's ending in this story:
Alfred about Thomas Wayne:
"He believed his example could inspire the wealthy of Gotham to save their city. Their murder shocked the wealthy and the powerful into action."
Will Bruce/Batman have the same fate as his father? Will he die and will his death inspire Gotham?
Rachel about Bruce:
"But I'm not sure the day will come when you will no longer need Batman."
Bruce can't give up his mantle or pass it to somebody else. He has to die as Batman.
Harvey Dent about Batman:
"You either die a hero or live long enough to see yourself become the villain."
We saw how Batman become the villian. Now he has to become the hero Gotham needs. The Dark Knight has to Rise. And when he dies a hero, his symbol will also rise.
Bruce about Batman:
"I can't do that as Bruce Wayne. As a man, I'm flesh and blood, I can be ignored, destroyed. But as a symbol... As a symbol, I can be incorruptible. I can be everlasting."
To stay as a everlasting symbol, his true identity must not be revealed.
Batman would never pass his mantle to somebody else when he is still alive. He dies a hero and nobody need to take of his mantle, cause he was the hero Gotham needed and he rescued the city. After his death the city can be rebuild by men without a mask. Maybe some people will find out, that Bruce Wayne was Batman (Gordon, Blake, Catwoman...), but none of them will ever disclose that, because they want to save the symbol he created and everyone still looks up to. The Bat-Signal will shine over Gotham as a monument, so every citizen will remember his legend.
