Beyond: I certainly agree that 4K HDTV's when they will come out will be specialty items selling at a very profitable price point for the manufacturers and retailers. However, I expect like we have seen with 3D HDTV's they will over time come down in price. This will be especially true if the profit from a lower priced (but still more expensive 4K HDTV), is greater than the profit associated with 4 23" to 32" HDTVs.

What I think could keep 4K HDTV's at bay is OLED with its much higher contrast ratio's and better color. Of course they are starting out at $8K. grin
