Earth 2 was the only thing stopping DC from reverting about the old universe with Robinson off the book and gone from the company. I guess his crossover planed for next year is off and to me this means DC is rebooting again after Trinity War.
Good point. I doubt they will revert though, they've simply got too much invested into the New 52 to just go back. But I wouldn't be surprised if a Flashpoint 2 happened that sort of set everything back after a fairly long aftermath either.
