I still think the others Earths shouldn't have Prime as a suffix like Earth-Prime does, Prime means center of importance, or first of many in the DC comics. That's why it was called Prime because it was the most important Earth as it was in the center. I think they should've gone with "Earth-2 (Post-Crisis)" instead of Earth-2 Prime. But I will let the admins handle it in time, the shows may even address this later on anyways.
