If rumor control is to be believed, there is a good chance that DC might reboot the Reboot the New52 that was created in 2011 that ended the reboot from the end of Crisis on Infinite Earth. One more reboot and every DC writer wins a trip to Dunkin' Donuts (now there is a question, what type of doughnuts do you think each writer eats?).
If this happens, what would you like to see DC do and why? Keep the new52 and do a Zero Hour type of event? Bring back the Post Crisis universe? Bring back the Pre-Crisis universe? Create a new universe? have both the New52 and another universe be used at the same time? Something else?
As I said in the latest postal apocalypse, I would have a story where the Flash by accident re-splits the the 3 fused universes which created the New 52 which results with everyone back in there Pre-52 universes. However, the time between the events still happened and everyone still has the memories of the new-52. so in 4-6 issue event, they defeat Pandora, create stable portals between the DC, Vertigo and Wildstorm and the new 52 universe becomes universe 53, so writers can still use it if they want to or choose to write in the old universe if they choose. Basically creating DC's equivalent of the Now and regular comics. fans of both win and writers get more freedom so they win.
