I think the PS4.5 wont run games at 4K but 3K

I'd say 2k is more likely. But open world games would probably go from 1080p 30FPS to 1080p 60FPS instead.

 

Edit: random thought.  

 

I wonder how long until 8k 240FPS will be possible on a VR device that costs under $1000. 

 

I wonder when 4k 60FPS open world games can be played on a 500$ or lower setup.
