why would i even waste time to guess? They ain't coming on until Charlie has a compelling reason to turn them on. Obviously, he hasn't needed to give new HD for many months. I surely don't expect the next 31 days to be any different. I'll get excited (or even interested) when they show up and have something i want to watch.
If I were a D* marketing rep, I'd be thinking..."hey! lets sell our HD offering on all those home shopping networks that E* just added! We can show them channels that have something people REALLY want to watch!" lol
