Van Jensen, half of the current Flash comic book writing team, has announced that he’s leaving the book after Flash #51.
As for the future, a bigger change is in the works. DC has teased some sort of “Rebirth”. Those original New 52 series are almost to issue 52. And another long-running creative team, Snyder and Capullo, are leaving Batman the same month.
There are rumors of a relaunch refocusing DC’s comics line to emphasize those characters who have the most media presence: Superman, Batman, Wonder Woman and Suicide Squad in this year’s movies, Flash, Arrow and presumably Supergirl in TV. This of course has led to speculation of a return to previous continuity, though that seems more like wishful thinking to me than anything solid.
That said, superhero comics are wrapped in an ever-tightening circle of nostalgia, with new ideas jettisoned for old ones on a regular basis. Whether you consider this a return to form or a step backwards depends on whether you liked the particular changes involved.
