I downloaded a 1 GB 6 minute video of killzone gameplay. I wanted to see how high of quality the ps4 goes. Did you know that Killzone was going to be 290 GBs? they had to completely rework the compression algorithms to figure out how to get it down to 40. This game has pretty amazing graphics. Still not Skyrim-but-heavily-modded levels, but amazing nonetheless.
Edit: Something I'm wondering is how within the next 4 years or so, Oculus wants to release a 4k rift. Sony is also designing an hmd for the ps4, so the ps4 will have to deal with rendering 2 images. I wonder how the graphics will look for ps4 vr games? Also, definitely another huge reason to get a ps4 over an xbox one.One will have vr, one won't.
The current rift is one display split optically. If they do a 4K rift, it will probably be the same; it will probably be 4K for both eyes, so roughly 1980x2160 per eye. Splitting a single display gets around lots of nasty synchronization issues. John Carmack covers it in detail in his 2012 keynote, if you care that much about the details. I watch them every year because I think he's fascinating.
A couple of other notes about rendering for the rift: Since it's only one display split in half, rendering for it is basically just putting a left eye image on the left half of the screen, and a right eye image on the right half of the screen. It's a little more complicated because the rift uses fish eye lenses between your eyes and the display. That increases the field of vision. Without the special lenses, it would be "like looking at the world through a pair of toilet paper tubes".
But since it's really just split screen, the rendering could be done on normal HDMI with software, just like rendering split screen multiplayer. The part that's special as far as I/O is the head tracking. When you are wearing the rift and move your head, your view of the world moves too. That requires getting the head tracking info from the Rift back to the console.
Overall though, I think if they want the Rift to work on the XBone, they could accomplish it without a significant amount of special hardware on the console end.
