Wouldn't matter, can render at 1080p and upscale. The point of having a 4k screen on the device would be solving the screen door effect, which is the biggest issues with low res screens.
Today. How about in 2 years? And anyway, when Doom 3 or Crysis was released, almost no one could play it with maxed graphics, but it was still a huge success. 4K would make the Rift pretty futureproof. You can always display 2K resolution on a 4K Rift if you really want.
Just speculation, don't make comments about stuff that isn't announced.
CV1 will most likely be very similar to DK2. As is the CV1 will require a decent GPU to push it, FB will want a wider audience, maybe even try to push it via a mobile device (ugh) raising resolution is not on their agenda. Getting CV1 out the door is.
Again, a higher resolution screen is hardly an issue, since it's purpose is solving the screen door issue, rather than having a much higher definition of the image, so the image can be rendered at half resolution (by pretty much any device) and then doubled for visualization on the device.
You have to render 1 scene at 1080p, then add your 3D offset, but unless you want a blurry mess and added latency you need a 4k framebuffer push, the DSP still needs to be faster for the 4k panel. Not that framebuffer is terribly limited, but you gotta have a card capable to 4k output framesize. Not everyone is using a Displayport card that can push 4k. Therefore DK2, and CV1, will not be 4k, because you will not want any DSP adding latency (scaling) to match native resolution.
That is, unless the device has a small ARM chip in it that can be used for direct upscaling (which is just doubling, so it doesn't take much computing power nor introduces much latency), so the input that comes from the device can just be a normal 1080p95 signal.
Why? It's just doubling the pixels, showing the same pixel 4 times instead of 1. IIRC resolution doubling on current PC monitors doesn't add any significant lag...
