Little side note. I feel that TV shows will never be broadcast in true 1080P. I heard from TV people that even at 720P resolution the make-up and props should be completely different. Nothing cheap could be used anymore because viewers can easaely see cheap backdrops and props. Actors also not too happy with us seeing their every pimple, wrinkle and nose hair.
that's a bandwidth issue. Right now they're broadcasting in 1080i and 720p afaik, both of which require substantially less bandwidth than 1080p. You should also consider that even at these lower resolutions, hell even at normal tv resolutinos, the cable and satellite companies tend to cram too many channels on to their available bandwidth, and so they over-compress everything and it ends up looking ******. You're right, 1080p will not be broadcast any time soon.
PS. If anyone actually wants to find out what resolution they should be considering, read the link i posted above. Read the chart and the paragraph below it.
