How do you guys think that Rebirth should fix the DCU and resolve the contradiction between the DCnU and the DCU now that we know:

spoilers:

a) Wally is back
b) Dr. Manhattan messed up the DCU for some reason and it's not really DCnU, but really our DCU ten years laters
c) Nu52 Superman isn't Superman and neither is the claimed Post-Crisis version, the JSA exist but forgotten, there are three Jokers etc
end of spoilers

For example how do you
a) restore the history of the Teen Titans,
b) fix the situation in Superman,
c) how do you resolve the contradictions in Wonder Woman and restore her old cast such as Donna, Artemis and Cassie?
d) how should they fix the Flash or Bart/Kid-Flash? What should they do with the old pre-Nu52 cast? Leave them in limbo? Or restore them?
