Note: Don't spoil anything past the Superman Reborn crossover.
I've been reading Superman, Action Comics, and a little bit of Batman and just thought of something.
I was surprised when I looked up New Krypton to see what had happened to it during The New 52 but found that the whole arc took place on New Earth and was Pre-New 52. So, when I looked up the DC Wikia page about it on Prime Earth, it did not exist!
So, here's my question: is it known if New Krypton does/did or doesn't exist on Prime Earth?
