I disagree. Sitting in front of a 28" 4K monitor would be MUCH more immersive than 12' from a 65". Not to mention, it just isn't comfortable trying to use a mouse and keyboard on the couch. Add to that, the impracticality of the Windows/Mac interface in 4K resolution from that distance. Maybe you'll see a small migration if the Steam Box catches on, but no major industry shifts without substantial changes.
