I just got AT&T HD about a week ago and the cable guy indicated that they expected more HD channels were to come online in the next month or two.
The cable box for HD is pretty slick - there are composite/S-video outputs for the VCR/Tivo, and if you use those, it doesn't even show the nasty digital cable menus on your recordings.
I was thinking of upgrading my service to this. My only problem is, I don't have a component input on my Barco I did however see a newtork input on the back of the box on diosplay at the Magnolia in Southcenter. Can the immage be sent via ethernet to a computer for display? If no, then I may have to look into a Y/Pr/Pb->RGBHV converter.
