The reason I asked is that some things said recently seem to suggest, for example, that the post-Crisis/NewEarth Superman and Lois still exist and that Lois is with child.
If the NewEarth/pre-Flashpoint realtiy morphed into the nu52 by way of it being merged, in the distant past, with two other universes, then the current (nu52) reality IS the post-Crisis/NewEarth realtiy, but with an altered history (due to other realities being blended with it).
How can the nu52 be an altered pre-Flashpoint reality, and yet the pre-Flashpoint reality is still out there, existing on its own and "doingverywellthankyouverymuch"?
Superman and Lois having a Son would be far more interesting then him and WW trying to fake a real relationship though!
Wonder how powerful a human hybrid would be?
