QFHD (quad full high def) was demonstrated by "Chi Mei Optoelectronics" back in 2005. I can't see this going anywhere anytime soon and didn't know about it until I saw your question. The industry is set up for 1080i and 720p broadcasts.

Anyway, you haven't seen anything yet even at 1080i. The HD video you are seeing on cable / satellite / off the air is a much watered down version of HD even at 1080.

They compress the video a LOT (by a factor of 150). If you saw the FULL HD (not the capability to display it that they are selling you but actually saw what the camera is recording) you'd be blown away even after seeing HD on your TV at home with HD on cable.

You see up to 20 Million bits per second in the broadcast. The camera records 3 Billion bits per second.

1080 means 1920x1080 pixels (over 2 million pixels). Each pixel has 12 bits of intensity information and 12 bits of color information for both red and blue (green is computed from the difference). This information for each pixel is stored 30 times per second. 1920 pixels (horizontal) x 1080 pixels (vertical) x (30 per second) x 12 bits of intensity x 24 (12 bits red + 12 bits blue) = 3 billion bits per second

It takes 3 billion bits per second to display FULL HD yet they broadcast it compressed at 20 million bits per second. Even when they store it on Blu-ray it is compressed video.

The compression sometimes is good but has a lot of defects in it. They only send the full picture every few frames and make up stuff in between based on what's moving etc. There's also some color averaging between blocks of pixels. I'm telling you the difference would be amazing if you saw the original video.
