This is different. That was two universes existing side by side. New Earth was "rewritten" during Flashpoint. The entire timeline has changed. It doesn't exist anymore.

Though, hypothetically, it's still possible to have a story set in New Earth (the Retroactive issues that came out 2 years or so back, for example), it's only the case if it's explicitly mentioned.
