I think these kind of threads pop up prior to every new generation.
Just take a look at TLOU on PS3
and compare to the TLOU 2 on PS4. And this is for a 7 year old console.
TLOU 3????
I can't imagine what first party developers can do with orders of magnitude better specs can do with this. At the end of this upcoming gen 8th gen is going to look a little dated again.
