I feel bad for anyone that hopes 60fps will be standard next-gen. It will just be like this gen, FPS games with a multiplayer component will be 60fps, fighting games and a majority of the racing games too. every thing else will be 30fps, or maybe 40fps with VRR.
The simple truth of the matter is that 60fps doesn't sell games.
I only miss 60fps, when there's an option for it.
E. G in god of war or gears 4, I will try the 60fps modes then go back to the 4k modes and miss the higher framerate, however when there isn't the option like in UC4 or rdr2 im not craving 60fps at all.
