The reason why I'm waiting next year for the 3080 series of cards
I am not sure things will change much by then, next gen games with more demanding graphics will be released, PC versions of those games will get even more demanding Ultra settings, and RT will be used more often. So the status quo will remain.
What will change is your ability to play current gen demanding titles comfortably. I saw you mentioned Witcher 3 and GTA V as examples of 30fps on PCs, in my experience the The Witcher 3 NEVER drops to 30fps even at 4K and HairWorks, it's hard locked to 60fps, GTA V can run sub 50fps on 2080Ti @4K if you use TXAA + 4X MSAA, it can drop to sub 40fps if you push 8X MSAA, but otherwise it's locked to 60fps as well. These are lightweight games.
What I am talking about are the heavy weight champions, games like Quantum Break, Control, Metro Exodus, Final Fantasy XV, Ark Survival Evolved, Watch_Dogs 2, Kingdom Come Deliverance, Agents Of Mayhem, Ghost Recon Breakpoint, Rise of Tomb Raider, Shadow of Tomb Raider and Red Dead Redemption 2 ..etc. These games barely sustain above 30fps @4K with max settings, which usually involve RTX, insane draw distance, crazy shadow settings like HFTS and VXAO or a combination of them.
We also have several CPU locked games, where you can never hope to increase fps because our single threaded CPU performance is not fast enough, games like ARMA 3, Flight X Simulator, Total War Warhammer 1, Total War Warhammer 2, and pretty much most Total War games too, in addition to fancy things like Ultimate Epic Battle Simulator, all of them drop to 30fps or even under that when the screen is filled with so many objects, and/or massive draw distances.
This forum is one of the only places where I actually see a PC gamer that opts to go 30 FPS.
Before my 2080Ti, I had a 1070, so I pretty much locked myself to 30fps @1440p in many of the above mentioned titles, because I only play at max visuals.
