Thankfully, phones are generally a sunk cost. Now the question is phone compatibility.
Gear VR will ONLY be compatible with the Galaxy Note 4.
Damn, not a sunk cost then. I think we have a note 10.1. Oh well.

From what I understand, the smallness of a 1080p phone screen makes 1080p seem a hell of a lot more crisp than a 1080p TV due to the PPI ratio. Because of the pixel density, a 4k screen resolution should be indistinguishable from a 2k resolution or perhaps even a 1080p. But we have heard people express the ability to see pixels at the 1080p so maybe the 2k resolution will do the trick? Hmm...

I would be surprised if 4k screens haven't already been developed and there just hasn't been a need for them when battery life is so important.
He! His holyness Michael Abrash said that in order to reach the same perception of detail of a full-HD screen in front of us we would need at least 16k. Per eye. Good luck with that..!
Did he account for the variances in PPI which are much higher on cell phones than TVs?
What we have here are experts contradicting each other. Not sure why I'd particularly go with Abrash as this isn't his particular field.
A 4k screen has around 110 PPI (Pixels Per Inch or Pixel Density) compared to 2k camera screens that have 490 PPI. Now, apparently the human eye can only resolve around 300 PPI from 10-12 inches away if Apple is to be trusted.
However, in researching the subject in response to you (thank you for following me down this rabbit hole), I've found someone do some actual math on the subject that discredits Apple:
http://www.pcmag.com/article2/0,2817,2364871,00.asp
That's one of the articles referring to Raymond Soneira showing how math shows that Apple is wrong. They actually put 480 PPI at the 10 inch mark.
However, a Discover Magazine blogger put out an article explaining why Soneira's data is misleading. Soneira uses better than 20/20 vision for the numbers he ran. He used .60 arcmin which isn't isn't 20/20, 1 arcmin is. So if you have better than average eyesight you'll need higher resolution to suit you if you're also a graphiophile.

So, for the average human eye the PPI of 300 for a phone being held around 10 inches away is indistinguishable from 600 PPI.
However, you and I are talking about the PPI of a screen that's only inches away from your face... So Abrash may not be wrong with 16k resolution being necessary. However, I don't know the exact distance the screen is from the eye. 1 or 2 inches off is a huge difference.
Also, we aren't focusing on the screen itself so much as focusing on the projected distant objects. This means that if we were to focus on the screen specifically we would see the pixels a little more clearly. However, the Rift seperates the eyes in a way that makes it impossible to focus on the screen but capable of focusing on the image it produces in the distance.
So there's got to be some special math done to figure out the science of humans looking at an object ultra close and how it relates to a 6 inch 1080p screen. I assume that it's noticeable but maybe it resting 2 inches or 1 inch in front of your face is actually less resolvable by the human eye than it resting 5 inches or 7 inches away?
Fascinating stuff. I wish we had an expert to have a quick conversation about this with.
