I'd agree that, when properly done, 1024x576p could probably match 
almost all of what is currently sent in HDTV today, especially if it was 
really in 4:2:2 format.  But, as you said, it mostly does not exist 
here.  And 720p is only 25% greater in each direction so it's probably 
close enough to have similar economics.

The intermediate resolution I miss would probably have been something 
like 1280x1080i or even 1440x1080i since I think this would be closer to 
"effectively square" pixels in a 16x9 format.   But I suppose I have a 
bias towards interlaced resolutions since most HD RPTV's like mine still 
use them.  This of course may change with new technology.
