Personally, I don't see the point in viewing a 4K 50" TV from 10 ft over a 1080p tv at the same distance. It would be even less noticeable than the difference between a 720p vs 1080p 32" LCD. What I am looking forward to is 4K HDMI 2.0 projectors, though I will have to run a new cable, a new HDMI switch box, a new HTPC, and a new AVR when that time comes. Will also have to upgrade my LCD, so that it can handle the same video stream as the projector.
