If by console optimisation, you mean turning down the settings from ultra to medium/low, yes.I personally think the new consoles can do high res at high FPS, console optimisation on the new projected hardware is gonna be something.
But I don't think we're getting true 4k and 60fps in the most demanding of titles in all honesty. Especially "next gen" games. Games graphics will continue to improve and get more complex so I still think they'll hover around the 30fps mark.
If I compare Witcher 3 4k on PC to my Ps4 pro... its still worlds apart.
