Starting April next year, Tyler Crook will be working on Harrow County (written by Cullen Bunn). My guess is it'll be a five-issue miniseries. I expect he'll still be busy with B.P.R.D. or Witchfinder though. He managed to to do Bad Blood between B.P.R.D. Hell on Earth: Lake of Fire and Witchfinder: The Mysteries of Unland, so he's certainly fast enough to do other projects in between his runs.
