Since we're guessing at specs ITT, here's mine:
PS5 in Nov 2020, $399
>10TF Navi GPU
8 core 7nm Zen CPU
16 GB GDDR6 w/ big bus
128-256GB boot+cache SSD
2TB 7200 rpm HDD
2x USB-C 3.2
Bluetooth 5.0
HDMI 2.1
2.1 compatible Blu Ray
Nip and tuck here and there if needed to hit that price point. I'm sure some devs will still want to push the boat out with the most impressive looking games possible at 30fps and sub4k, but I wouldn't be surprised if Sony urges more of their own studios to target 60fps (or at least have performance modes) for more VR compatibility.
