[According to Comic Book Resources article, it is alleged that those covers appear to hint at the “5G” event that former DC Editor-In-Chief Dan Didio was planning. That event was meant to cover five generations of DC history, starting in the 1940’s and leading up to the present day. Elements from this pitch have appeared in DC’s Generation Zero one-shot.]
