Drifting off-topic, but those are 'raw' data rates. Compression algorithms along with motion-estimation allow you to get full-screen video down to ~1.5 Mbps with not much in the way of image quality loss.
Raw HDTV is about 1.2Gbps. RAW NTSC SDI bitstream is a few hundred. The 6 and 19.8 are already compressed. Obviously putting more horsepower to the compression you can achieve smaller data rates. However applying for example MPEG4 instead of MPEG2 for 1080i or 720p ups the computational requirements beyond current consumer state of the art.
I think you'll see it long before every house has fiber run to it.
75% is enough. Pete
