Now what I was wondering if this is Earth One than what Earth dose the all the other comics take place? I thought that the new 52 was pre-Crisis Earth One? Dose everyone else know something I don't?

@luther22:

The Current New 52 stories take place on Earth-0 (or prime if you prefer)

@Afro_Warrior: thank you for clearing that up.

@Afro_Warrior: @luther22: Has it ever been stated that its designated as Earth-0/Prime? I thought it was still New Earth. Article??

@ArturoCalaKayVee:

I was under the impression that New Earth/Earth-0 and Earth Prime were all being used as descriptors for the current DC Earth.

@Afro_Warrior: I have no idea, that's why I was asking. I'm still used to Earth-Prime being Superboy-Primes earth so it seems weird to me even though SBP was written out of existence.

@ArturoCalaKayVee:

Honestly, i'm not sure if DC is certain yet. The crisis's are out of continuity which suggests that so is Earth Prime, but Batman still died and came back to live :s For now i'm just working with what's been used so far (i.e. Earth-0/New Earth/Earth Prime all being the current DC Earth) and trying to ignore past continuity unless its been confirmed within a comic or by a writer/editor.
