While I appreciate snazzy tech as much as the next guy, or possibly more so as I have an active academic interest in it, I feel like nowadays graphics come more down to good optimization and art direction than raw power.
I don't think there will ever come a day for example when I look at Trine 4 and think "ew, this looks like crap". Heck, I still think Mario Galaxy looks great and that's a 13 year old game running on overclocked 2001 hardware.
So while I am interested to see what new technological advances can be made with PS5 and Xbox Series X, I'm more interested in how that power can be applied to create more interactive worlds and emergent gameplay than how many polygons or pixels they can push.
