For about a week now rumors have been swirling about a PS4K, and Sony has confirmed this is a device with a working prototype. Regardless of what Sony is currently reporting, there is not a modern GPU small enough to fit into a game console to promote a jump from 1080 to 4K while maintaining 30fps. The numbers that have been shared do not feasibly justify us believing this jump is possible. However, what is far more likely is a 4K media playback. This gives Sony an edge without shelling out money on CPU upgrades that could also cause problems with backwards compatibility. Sony already has the best console on the market; if Sony only upgrades minimal hardware and media playback they will only put themselves further in the lead.
