I don't forsee an event like COIE. I can envision a Crisis of Infinite Forgetfulness.
What do I mean?
I can see Batman reduced to:
Alfred
Gordon
Batman -Bruce
Batgirl - Barbara
Robin - Damian
Batwoman (she has a show.)
Nightwing (cause it's Grayson.)
Red Hood (maybe)
What do we need Tim, Stephanie and Cassandra for?
I see the latter 3 disappearing into comic book limbo.
I see a lot of history disappearing into comic book limbo.
Killing Joke, Death in the Family and many other stories never being mentioned again. (They are not erased; they're just ignored...along with most history.)
The stories we will get: Batman & an ally versus the villain-of-the-issue/story arc.
Maybe I'm wrong. It's just a feeling.
