After years of hinting that Sons might get a spin-off, EW has learned that series creator Kurt Sutter is now in the preliminary stages of developing a new show set in the Northern California motorcycle club scene.
Details about the project are scarce. In fact, we only know one thing for certain about the proposed storyline: The project focuses on the Mayans the Oakland-based Hispanic MC gang that had quite a rocky history with SAMCRO across seven seasons. In the original series, the Mayans run heroin factories and are also involved in prostitution. Their cuts bear the legend Los Asesinos de Dios Assassins of God.

Sutter will executive produce the as-yet-untitled project, and is currently hunting for a showrunner to handle the Mayans day-to-day management.
