Over on the Nerdist, DC released the covers for the upcoming Superman: Earth One Volume 3 and Batman: Earth One Volume 2. We also see that art change as the 3 volume of Superman: Earth One is going to be drawn by Ardian Syaf, replacing Shane Davis who drew the first two volumes. These two books won't be out until 2015.
