Polyphony over-specced Gran Turismo Sport for future 8K consoles
Also, one user (media outlet reporter) whom was at the CES asked about the hardware running the demo, they we're told "at this time, we're not at liberty to provide that information." Doesn't mean much, but don't kill the messenger.
As an FYI: Sony has done something like this similar in the past with Polyphony.
Polyphony over-specced Gran Turismo Sport for future 8K consoles
During the studio tour, Kazunori Yamauchi took us from desk to desk, showing his staff beavering away on the game and the insane amount of detail the team goes to make the experience authentic. It’s really quite insane. At one particular desk, he zoomed right in on the wheel of a car to show the small-type – like the PSI – was in place and legible. A ridiculous detail given you’ll never notice at 300km/h flying down from the heights of Mount Panorama. Then he said the following: "It takes six months to create a single car. It’s over-specced for PS4 Pro. So we are building for future versions of the console rather than the one we see today".
