I don't think base PS4 is powerful enough to do 900p60 across most titles. Not without significantly lowering game detail to a point of blandness.
720p60 would be possible.
IMO Sony should have made standards since the beginning.
Base PS4: 720p60; 1080p30
PS4 Pro: 1080p60; 1440pC30;
e=mc^2

Gaming on: PS4 Pro, Switch, SNES Mini, Wii U, PC (i5-7400, GTX 1060)
