PS4 cannot do 4K at anything over 24hz, it does not have displayport, just HDMI1.4, which can support 4k but only at 24hz, which would look awful.
The increase to 4k would require more video memory than the PS4 has available for anything other than a very basic game but given that the ownership rates of 4K displays are less than 0.1% worldwide right now, no studio in their right mind, first party or otherwise, would waste their time optimizing a game to run at 4k when no matter how well their code is, it would be limited to 24hz, and you could fit the global population of 4k display owners who might buy the game into a single room.
If you continue to spout nonsense about the possibility of 4K on the PS4 for anything other than trade-show tech demos (a-la 4 screen GT4), i will be forced to assume you rode the short bus.
