This arc will kick off April next year with art by Laurence Campbell. We don't know much about this series at the moment, except that it will feature Johann prominently. Scott Allie had this to say about it and writer John Arcudi:
He's also mentioned it in Hellmail too at the end of The Devil's Wings arc:Arcudi’s biggest contribution to Mignola’s world is to populate it with living breathing people. Unfortunately, they don’t always stay living or breathing. They deal with the mortality of their own teammates too often, and for most of them it doesn’t get easier. Johann’s blurry relationship with mortality comes into focus because it’s gotten too easy for him to accept the deaths of the people around him…
Makes sense too considering this will eventually fill the 12th B.P.R.D. Hell on Earth volume, and they're clearly writing with omnibuses in mind since all the biggest stories happen every third volume. (3. Russia, 6. The Return of the Master, 9. The Reign of the Black Flame) It also seems like a good place to see this come to fruition...Laurence [Campbell] has really proven himself as one of our go-to guys for a good creepy tale. While he's taken over as our regular cover artist, you aren't going to see him on interiors for a little while, as we're saving him up for the biggest story since the end of the Plague of Frogs saga.
