Perhaps you haven't heard of the 1080p24 and 1080p30 formats that are 
/required/ by ATSC ( http://www.hdtvprimer.com/ISSUES/what_is_ATSC.html 
).  Are you sure no one is broadcasting in 1080p24?  While I don't know 
of any broadcasters changing resolution (i.e. from a 1080 resolution to 
a 720 resolution), I /do/ know a lot of them change refresh rate (i.e. 
commercial breaks often have video at different refresh rates from the 
program).  IMHO, it would make a /lot/ of sense for a 1080-res 
broadcaster to broadcast a movie (i.e. filmed at 24fps) in 1080p24 
rather than telecine the content to 1080i60, though I've never checked 
to see if any do.

That said, many TV's do not support 1080p video through Component, so 
there's probably a lot of STB's, etc., that won't output 1080p via
