Not anytime soon IMO. If it does happen it will be due to some new tech/game innovation which is a data hog. 4k will not be that tech as far as I'm aware, as graphics improve we're less reliant on pre-rendered video and 4k quality assets =/= 4k video. If anything I say most in game asset nowadays are more detailed then what our current resolutions allow us to appreciate

A lovely gif of Nathan Drake's chest for y'all ;)
