A next generation is coming and, as always, we're still in the hype phase where companies boast about 8K, 120FPS and whatnot, but the fact that next gen consoles will be able to hit 4K in most games seems pretty accepted given that the much weaker PS4 Pro and Xbox One X already can hit that in a couple of titles. And yet, while the added crispness it adds to the image is undeniable... it's kinda hard to justify jumping to that resolution in my opinion considering the huge performance hit. Of course, 720p to 1080p was a huge performance hit as well no doubts, but that was a much more neccesary jump than 1080p to 4K on small/mid-sized screens (under 50'), in which that lost power would be much better utilized into faster framerates or better settings, in my opinion.
With next-gen consoles having ray-tracing capabilities, I'd much rather take a 1080p game with fully ray-traced global illumination, reflections and the extra shit than a 4K game with reduced or no raytracing at all, and on PC short of supersampling shenanigans it'd be such a waste to play at 4K considering the sizes of most monitors. But that's just me of course, maybe people really like them pixels, and I'm sure console manufacturers will obviously go for what's easy to market so we'll probably even see a few 8K games here and there.
