King (formerly HRH Crown Prince) Salman is the last of the Saud line of Wahhabi. There's going to be a lot of jockeying around for who gets named Crown Prince and where their political support comes from (besides BHO).
Wahhabi are fundamental Islamists like snake-handlers are fundamental Christians.
