DC Entertainment co-publishers Dan DiDio and Jim Lee both tweeted out the following image today, along with the caption "#Rebirth":

There's no context to the image, but some speculate DC is planning a linewide relaunch of their books, based on a rumor purported by Bleeding Cool that says the publisher wants to dominate their line with "'Batman,' 'Superman,' 'Wonder Woman,' and 'Harley Quinn'/'Suicide Squad'-related titles," in light of their burgeoning big screen universe.

Of course, the specific word "Rebirth" carries a certain weight in the DCU as silver age heroes Barry Allen and Hal Jordan both returned to main continuity in the "Flash: Rebirth" and "Green Lantern: Rebirth" mini-series, respectively -- both written by Geoff Johns and drawn by Ethan Van Sciver. Could this new image be teasing one particular character's return?

CBR reached out to DC for comment, but has yet to receive any confirmation.
