Most of that sounds pretty reasonable.
That CPU boost will be the most interesting part, imo.
I'm not phased too much by resolution having to be full 4k (I think dynamic res does a great job, and CB rendering is a brilliant solution until you're comparing side-by-side stills zoomed in) and I do love games at 60fps, but I'd honestly be content with a solid locked 30 and some crazy awesome physics going on in some games.
When PhysX was announced there was a game, albeit a crap one, that had amazing cloth and particle physics, with people flying everywhere and s*** blowing up. Now that CPU's are getting better, and with consoles FINALLY making a leap forward, I really hope that the games take advantage of this.
Ass Creed Unity bit off more than it could chew, but it was a step in the right direction. The idea of GTA 6 being able to do something similar on a next gen pumped up system seems so exciting, but I hate the idea that we're just gonna end up with GTA5 at 4k 60FPS with new effects.
Even Farcry 5 felt a bit stripped back in the way that animals and outposts interact. The AI felt idiotic, patrols just seemed to be charging towards you...
And I guess I kind of worry about a previous gen dragging future games back with them too.
Imagine having the Alien from that Alien game thrown into PUBG without the game running like bollocks.
Blergh, I'm super tired and I don't even know what I'm trying to say at this point... I guess we're going to end up with the exact same games at 4K.
