Not sure if this theory has been posted, but....
This is the New 52's future, and it's post-apocalyptic
Thus it will most likely require time-travel or something to ensure that it doesn't happen.
Which means we might have another crisis situation where the New 52 timeline is altered, giving DC the opportunity to discard anything they think didn't work in the last 3.5 years and bring back what fanboys missed (like ginger Wally), and to potentially rebrand and to use #1's again if they wanted.
I'm not anti-New-52. It's just a thought.
