Earlier today, Sony announced that they have given their official license to two different third-party pro controllers. These aren't exclusive to the PlayStation 4 Pro, they are merely called "pro" controllers. One comes to us courtesy of Razer and the other comes from Nacon.

Let's see what Sony's Andrew Mason has to say about these two offerings, the Razer Raiju and the Nacon Revolution.

Nacon Revolution
Developed with the eSport player in mind, the Nacon team of industrial designers and engineers collaborated with pro-gamers to develop the Revolution Pro Controller to meet a wide range of their gameplay needs.
