We present our ongoing radial velocity and metallicity survey of the halo and the inner/outer disk interface in the M31 galaxy, using Keck/DEIMOS. We highlight new detections of the extended disk, the rotation curve out to 70kpc radius from stellar kinematics, the underlying halo component, and several new kinematic substructures.
