"We are developing high-end PlayStation 4," said a Sony Interactive Entertainment spokeswoman.
The new model will have processor and graphics upgrades, as well as support for 4K resolution games, Sony said. Support for Ultra HD 4K Blu-ray discs was not mentioned, but may be included.
The new PS4.5 will also cost more than the current PS4, which starts at $350. The company declined to give a price or release date at this time.
You'll be able to play any existing PS4 games on the new system.
Currently PS4 and Xbox One games output at 1080p.
