In November last year, DC Comics published Superman: Earth One by veteran writer J. Michael Straczynski, which told the story of a younger version of Clark Kent.
Following the success of Superman: Earth One, DiDio has now said that there are plans in place for further original graphic novels along the same lines.
"I think the success of Superman: Earth One shows that particular types of stories work well in particular markets," he told Newsarama. "Superman: Earth One was like a feature film, where the Superman comic is more like episodic television."
DiDio claimed that bookstores are now seeing more and more episodic novels akin to the Twilight series, and admitted that DC Comics will be trying to capitalise on the trend in the New Year.
"We did announce that we're doing Batman: Earth One with Geoff Johns and Gary Frank," he added, before confirming that Straczynski and Shane Davis are already working on a sequel to Superman: Earth One.
No release dates for the next entries in the Earth One line have been announced.
