Paizo will release the "setting" book Pathfinder Lost Omens Gods & Magic and launch the new Extinction Curse Adventure Path in January.

Pathfinder Lost Omens Gods & Magic is a setting book that provides background on the pantheon of deities for characters to worship or fear. This book contains details on the gods and non-deific faiths from the Age of Lost Omens from the point-of-view of clerics as well as lay-worshippers, and also offers new domains, feats, and spells for characters. Pathfinder Lost Omens Gods & Magic will be 128 pages, and will retail for $34.99. 

Extinction Curse: The Show Must Go On will be the beginning chapter in a six-part Adventure Path, with a different chapter released on  a monthly basis afterward. This Adventure Path is intended for four first level characters, and the plotline revolves around a traveling circus that unravels a plot to eradicate all life from the Starstones Isles. Each part of the campaign will come in full-color softcover, and will carry a MSRP of $24.99.

Paizo recently announced two more titles for Pathfinder Second Edition (see " More Monsters, Gamemaster Resources for 'Pathfinder'").
