David,
Our planned release schedule looks like this:
Vol. 1, 1-3 (September 22)
Vol. 2, 4-6 (November 24)
Vol. 3, 7-9 (January 19)
Vol. 4 10-12 (March 9)
These are PDF release dates, with physical rewards 1-2 months behind.
Each volume will be launched with a 30 day Kickstarter (first one we did 60 days for initial exposure), before being made available on DriveThruRPG.
Each volume will take between 10-12 four hour sessions to complete for an average gaming group.
Paul and Angry,
Thanks for the support!
