console graphics are run by graphics card designed for PCs, and as of the moment, there are no single graphics card that are capable of running at max settings at 4k resolution and with HDR.
And also when ps4 and xbox one was developed, it only had GPU thats equivalent to a midrange PC GPU. Sony and MS will not put a high end GPU. So, its safe to say a PS5 is probably 3-4 years away.
Maybe that's why, SOny has released the PS4 Pro and also MS will have "Scorpio", coz they know it will take a while before grpahics companies come up with a good enough GPU for 4k gaming. And mind you, they haven't done that before, they only had a PS3 slim version with same processing power.
Getting a "updated" PS4 Pro now, I think is a safe bet, since future early PS5 games will also come up with PS4 versions, and graphics will still be good for 1080p gaming at 60fps, which is still good enough for most people.
