Doomsday Clock is moving to a new release schedule following two back-to-back skip months.
Originally scheduled to have skip months in March and August (according to Geoff Johns at Comic-Con International: San Diego 2017), Doomsday Clock will now begin shipping every other month beginning with an anticipated #5 in May 2018.
""Sorry. It was always foreseen that there would be a break between 4 and 5. But no one wants to miss shipping or have to cut back on the complexity," Frank tweeted after Newsarama's initial reporting. "I'm hoping that we can use this to get enough of a cushion to switch back to monthly at some point."
Doomsday Clock #3 remains scheduled for January 24, and #4 on February 28.
