Depending on game per game basis. Racing, sports, fighting, 2D platformers (especially the arcade, not puzzle ones), fast paced gameplay shooters I would probably rather have in 60fps. Everything else give me 1080p and stable 30fps and I'm good to go.
Ohh and I would wait for DF analysis over believing some random site, that I doubt have means of directly counting frames.
So it is happening...PS4 preorder.
Greatness Awaits!
