From the announcement:
Advanced player vs. player mechanics come to the leader in table-top Roleplaying. Conflict Games has released for pre-order the Conflict PvP: Tactics and Teams rulebook for the Pathfinder Roleplaying Game© and d20 fantasy games. This RPG supplement provides the framework that allows table-top team vs. team or player vs. player competitions that are playable, fair, and fun. Conflict PvP integrates directly into the Pathfinder Roleplaying Game©, which means current players can step right into deadly competitions with their existing characters or one of the 30 preoptimized characters the book provides.
