If we go by what the press releases say then Spaceway 1 and 2 will be used for HD LIL. The wild card is the Ka payload on DirecTV 8. There are no press releases stating what it will be used for. I am guessing it will be used for new national HD channels and NFL-ST HD games.
Kfried, Cox in PHX just added KSAZ-DT (FOX), KSAW-DT (WB) and INHD2. They have had INHD, STARZ-HD, Showtime-HD, HBO-HD, ESPN-HD and Discovery-HD for a while now. They do not have Cinemax-HD.
