Also Known as the PS4 Neo and PS4.5
"PS4 Pro is a high-end version of PS4 that is capable of outputting 4K graphics, HDR support, smoother and more stable framerates, and 4K video streaming. Upon its launch, PS4 Pro will make supported PS4 games look better and run more smoothly, while giving developers an upgraded toolset to create even richer, more detailed game worlds. How these powerful new tools are used is up to individual developers and the experience they are creating."
