I don't think it will (Or should) happen, though. DC wants to keep Grant Morrison happy, and Grant Morrison planned to kill Damian the moment he invented him. He grew to love his creation, but Damian's death is important. It brings Batman back to zero, a ronin of justice in the shadows.
The problem with comic books is they are never supposed to end. It's the same reason soap operas see so many people back from the dead. The story is supposed to continue forever, and almost always returns to its original form or most popular form. Comic book Batman is rarely without a Robin.
The question is, "Is Damian Wayne's death a defining moment for Batman as Uncle Ben's was for Spider-Man, or can it be rewritten without destroying the character of Batman." Bruce Wayne really became Batman the moment his parents died, the moment his young mind rejected the ability of criminals to take lives if he could prevent it. The loss of a son could possibly have that same effect on him, and part of me hopes that it will become as defining a moment for him as the murder of Thomas and Martha Wayne.
Not many superheroes lose a son. As a grown man, surely Batman's rage against his parent's death has dulled. The death of a child? That is a fire that never, never goes out. If Bruce Wayne chooses to continue to be Batman so no more children die like his son, it will be a beautiful, terrible thing to behold.
One final note... I always remember Neil Gaiman's Sandman story "Façade." It dealt with a long-forgotten sidekick, Element Girl, who was living alone and afraid after her career was over on disability checks and getting by on a single phone call from an agency as her contact with the outside world. Her powers made her effectively immortal, but her life had no purpose anymore.
It's an amazing story, and in many ways mirrors the world of comic book characters themselves. Sometimes we drag these poor creations along far past the point when we should have allowed them to rest. Long past a point when death was a tragedy and not a release.
Sometimes a story isn't real until it's over.
