Superheroes never die ...
... permanently.
Granted, a few members of superhero groups have died permanently (or, rather, they haven't been resurrected yet), but superheroes with long-running solo-titles and high name recognition are never gone for very long.
It has happened, though, that the person behind the mask has changed. Even Batman was for a while someone other than Bruce Wayne. So a possibility is that they will (more or less permanently) kill Bruce Wayne and have someone else take up the uniform and name after a suitable time, with DC announcing The All New Batman, Like You Have Never Seen Him Before.
Additionally, both Marvel and DC are known for occasionally making "resets", where they write off all that has happened before, starting all their titles over from scratch. So after killing a suitable number of heroes, they may announce The All New DC Universe, Like You Have Never Seen It Before.
In other words: Yawn, what else is new?
