The update is here with the increased aberrant chance event. The new corrupted weapons are Cube Gun, Sorrow, Arbelest, Nebula and Savior. I've only gotten the Corrupted Nebula so far but I love it. It becomes a semi auto laser pistol that spawns the nanomachine swarms from the mod of the base gun on weakspot hits and its mod blows up the nanomachines for decent damage and a good Corrode. I haven't unlocked the base gun yet but apparently the Corrupted Savior is the return of the Fusion Rifle from 1 which Savior was a reference to to begin with which is really cool.
