Correct me if I am wrong, but if I remember correctly Dr. Manhattans first appearance in all of this was back at the end of Darkseid War, where he killed Owlman and Metron. Then we see him in the DC Rebirth special where he kills Pandora. All three characters: Metron, Pandora, and Owlman seemed to know who he was. Although that could be because of the mobius chair that Owlman and Metron sat on, which gives infinite knowledge. It could be said that Dr. Manhattan was the outside force that caused Pandora to merge the timelines creating the new 52. But this issue of DDC went against that. Are these plot strings something I should give up on, or do you think Geoff Johns will resolve them?
