With the ongoing pandemic, shipping is still a bit of a mess. As such, knowing when figures and games will be released is a bit of a guessing game. At the moment, WizKids and Paizo are looking at October 6th for the upcoming Pathfinder Battles: Bestiary Unleashed set.
From the announcement:
We have a new release date from WizKids for their Pathfinder Battles: Bestiary Unleashed pre-painted plastic miniatures—October 6. You can find them at your favorite local game store and the Paizo Store soon!
