Citing multiple sources, Kotaku says that Sony is working on a 'PlayStation 4.5.' The gaming console will supposedly have an upgraded GPU which will support high-end 4K resolution for games, and have more processing power which would enhance the games supported by PlayStation VR. From the report, "A more powerful PS4 would also allow the machine to be more competitive with PCs in the world of virtual reality. With a higher-end GPU, the PS4 could more easily match up against the more expensive Oculus Rift and HTC Vive virtual reality headsets, which are designed to work with powerful PCs."
