Yeah, and I see what you mean there. I think even when the PS6 comes out, game developers largely won’t be taking advantage of its capabilities just like how today they don’t really leverage the capabilities of an RTX 5090.
We saw with much of the PS5’s lifespan that many of its cross-platform games came out on PS4 and original Switch with minimal compromise.
Not enough of the install base owns those higher end solutions, so for the most part someone with a better performing rig is getting better FPS, higher resolution, and not much else. Even gaining additional draw distance is rare these days, and higher resolution textures are basically impossible to see.
If the console is going to survive rather than decline as a whole I think that Microsoft and Sony will need to get more serious about innovation rather than just making a samey spec bump at a high price that doesn’t motivate their users to upgrade. Nintendo already proved that basic and rather mild level of innovation can excite the market (original Switch).
