I am not sure what makes anyone think they will ever bother bringing back New 52 Superman, it looks to me like they are really trying to wipe him clean out of the picture. Yeah, it's disappointing that they don't seem to do much with him on his own but figure that hey, let's dump truth on him, let's dump Doomed on him, etc. Looks like DC hates the guy and just used him to get some interest in the character.
