From the article:
In the month since we announced our latest class playtest, there’ve been rumors, speculation, and Pathfinder fans across the internet connecting the threads of what the next book could be. Appropriate, since I can now say that our newest rulebook will be the paranormal Pathfinder Dark Archive, releasing at Gen Con 2022!
Golarion is a fantastic world filled with the impossible. A city returned from the depths of time. A chasm to the Abyss, only recently sealed. A fallen star granting godhood. Yet even in a world where anything is possible, there are always further depths and stranger phenomena on the fringes of understanding. The Dark Archive contains material for players and GMs alike to bring cryptids, temporal anomalies, and other paranormal phenomena to their game tables. And of course, two new character classes that investigate the unknown: the psychic and the thaumaturge!
