"Select titles will get doubled frame rate (30 -> 60, 60 -> 120)"
Am I the only one who thinks certain games SUFFER from pushing 60fps? Specifically, story-driven/cinematic games? I think it might be one of the main reasons I found it hard to get into The Last Of Us, because I played the PS4 remastered version and all the in-game cutscenes were smooth as a fighting game. I much prefer 30fps for those games, it looks more like a movie, which it's trying to convince me it is.
I find it very similar to motion-smoothing features on a TV, or the "soap opera effect" as it's otherwise known.
I don't agree. I've yet to play a game that I felt was being negatively affected by having a higher framerate, as long as it's stable. I'm much more sensitive to other effects if they're poorly implemented, like motion blur or some of the post processing effects out there.
I get the point you're making on a cinematic feeling, but if a studio really cares about this they can choose to lock framerates during cutscenes. I haven't really heard of this phenomenon in western games beyond pre-rendered cinematics sometimes being stuck at 30, but Ark System Works did it with Dragon Ball FighterZ's super attacks. It goes from 60 FPS gameplay to 24 FPS for animation to emulate the anime.
Really if anyone was going to put too much of a focus on a cinematic feel it'd be Naughty Dog, so you might be out of luck there. Hopefully way more games will start to give an option between a performance or graphics option on next gen so we both can get our preference, though it's hard to know if it'd lock all the way down to to 30.
