The blatant connection to Superman Red/Blue that they have, and strongly insinuating that they're both part of a whole.

With this solicit:
Not to mention that the whole deal about Rebirth is that ALL of the heroes are the same as they were Pre-Flashpoint, they just don't remember it. Somehow, the Superman are two different characters, which gets me to the above point.

Then you also account for the changed costume..
I'm 95% sure they're merging, and I really hope that's the case.
Oh wow. I haven't seen that cover or those solicits yet. I can definitely see what you are saying. Its kind of neat seeing the two Supermen drawn together. I hope they don't do away with Lois. When Wally returned, I was wondering how the two Supermen would play out.
Thanks for posting that.
God put me on earth to accomplish a certain amount of things. Right now I am so far behind I will never die.
The merged Superman should be the Authentic Superman-- the Pre-Crisis Superman with full memories of his entire history from the Golden Age, SILVER Age, Post Crisis, Post Zero Hour, Post Birthright, Post IC, And Nu52 integrated. Anything else is another continuity error AGAIN.
