At the DC Metal panel at New York Comic Con, Greg Capullo revealed that he's been a little sick while working on Metal, so DC is giving him the month off. In February, between Dark Nights: Metal #5 and #6, we'll get Dark Knights Rising: The Wild Hunt, presumably focusing on the titular evil Batmen. Scott Snyder, James Tynion IV, and Joshua Williamson will write, with Doug Mahnke and Ivan Reis on art, and a cover by Mahnke.
Capullo said the one-shot gives him room to be on each issue of Metal, which is the way we'd all prefer it too. And it's similar to the break John Romita Jr. got during Dark Knight III: The Master Race, so there's precedent.
Bleeding Cool ace reporter Joe Glass is on the ground at the panel, and he'll be bringing us a full report later. In the meantime, stay tuned to Bleeding Cool for breaking news from NYCC 2017.
