Disappointing? Yes and no, to me. In this very generation we're already achieving 4K or pseudo-4K solutions, and some other games are prioritizing framerate too, so it's natural that people want this what we already have (despite the compromises) as a standard... but without those compromises, or not all of them at least.
And yes, to me, because I still think that a game with better graphics and perfect AA in a lower resolution (nowadays, a lower resolution still implies HD or higher, nontheless!) or with 30 fps (with the exception of MP and sports games, maybe) is preferable that a game with worse graphics but in 4K or 60 fps.
I don't think there will be a huge difference in the variety of developing focuses in the next generation: some devs will prefer one way or the other. Some devs will prefer to offer better graphics even though 30 fps may be questionable for some people, other devs will offer what some people would call a better gameplay experience at a higher fps rate, and other devs will opt for a sweet spot in between.
