Ok stop spinning for a moment, now I'm talking about
THAT EXACT DEMO WITH THE EXACT ASSETS QUALITY AND PERFORMANCE. Can you now provide a proof that same demo at the same level/performance will work outside PS5?
All effects will work on other devices, might as well androids and iPhones, but they'll scale down.
On other platforms, it looks like Unreal Engine 5 will just scale down, although it's not clear to what degree it'll scale down on each platform.
Epic's Tim Sweeney hints at what's to come in 2021 for new consoles, Fortnite and more.

Saying that exact demo will run with the exact amount of details and performance on XSX is a fairy tale. Lumen, Nanite etc will work everywhere and scale according to HW capabilities, no one even bothered to say otherwise.
EDIT:
Tim Sweeney said this demo is running on "the best hardware that will be available at the end of the year":
