What's interesting about this is that the tech has been proven dating back all the way to 2007 [1] and also re-implemented by enthusiasts many times over the years with better eye tracking via CV. What Sony has done here is refine it and package it in a way that's nice for end users.

Personally, I'd like to see this implemented more cheaply in larger displays to act as virtual windows for indoor environments, like [2] from 2010, but with 3D video/rendering.

I was hoping the first link would be Johnny Lee... He was a true pioneer and hacker in this space.

From what I understand the display is still stereoscopic so you will see a separate image for each of your eyes. Johnny Lee's demo was just a regular image with view-tracked parallax. It looks really impressive in a 2D video demo, but you'd immediately notice there's no depth if you saw it in person.
