Mansions of Madness 2nd ed. base game and all expansions have sold out! No reprints in sight! Could The Path of the Serpent be the last expansion we see?

MoM isn’t coming to an end. FFG just made new sculpts and molds for the figures in the core set. You don’t do that unless you plan on making sets for a long time to come. It may be out of stock at some places but it won’t stay that way.

Historically speaking FFG’s Upcoming page is, at best, an unreliable predictor of what is going to be reprinted.
