Will I see more copies of this expansion in stores now that the 2nd edition is coming out? Or are there plans for a newer expansion post-2nd edition?
This edition of Archfiends runs with 2nd Edition. There is not yet anything in the works for a newer version of Archfiends - we've got to sell the one we made already first.
As for your first question: We hope so? As any game company would, Game Salute is attempting to make it available anywhere that will stock it. I'd certainly like it if a lot of places stocked 2nd Ed Shadowrift, and Archfiends and Sickle Moon as well.
