The company also revealed a PS4 Slim, the same as the existing console but in a much reduced size.
Sony has released a new PlayStation – and perhaps cleared the way for far more to come very soon.
The new console, named the PlayStation 4 Pro, features 4K gaming for the first time on any mainstream console.
It will also allow players to watch videos using high dynamic range (HDR), a TV technology that makes videos of a much higher quality. Games will also be able to use that technology, another first for a mainstream console.
