"The 26 best-selling DC single issues were all written or co-written by either Geoff Johns or Grant Morrison."
--Techland's Douglas Wolk makes a startling observation about Diamond's 2010 sales charts. I mean, I knew Johns and Morrison were DC's two bestselling authors by a long shot, and since I enjoy their work a great deal I'm pretty happy about that, but that level of dominance is really stunning to me. Moreover, Wolk goes on to note that "The best-selling DC single issue that was neither a Batman comic nor a tie-in to Blackest Night/Brightest Day was Superman #700, at position #109." In other words, DC's dominant writers have made the properties on which they work -- predominantly Batman and Green Lantern -- DC's dominant franchises as well. Even superstar writer J. Michael Straczynski's much-ballyhooed Superman debut failed to gain much traction relative to the Johns/Morrison juggernaut.
I think it's safe to assume that Johns is being pulled in more and more directions by his Chief Creative Officer duties -- the same position, keep in mind, that Joe Quesada recently relinquished his Editor-in-Chief gig to focus on over at Marvel. Meanwhile, Morrison is a writer whose work meets with frequent delays at the best of times, and who has a full slate of creator-owned work and various media projects (Hollywood screenplays and adaptations, the indie flick Sinatoro, My Chemical Romance videos, etc). Finally, there's no way to tell how the Green Lantern movie will affect fan interest in the franchise. That's a lot of eggs to have in relatively few baskets.
