How much capacity for HD is there with existing satellites? Really? Two channels? Four maybe?
Other than that, there won't be anything significant until June or July. The new Echostar Satellite Launch looks like Q2 at the absolute earliest unless sealaunch weather improves in the next few days. Not sure when the AMC sat is scheduled, but I could not find any schedule reference to it through next June. They can't move anymore because they need the rest to absorb peak sports demands.
In the meantime, the best we can hope for is to move a couple of PPV channels to Internet based VOD.
If you want GObs more HDTV, you are going to have to move to D*. I have not decided to do that yet, but when the 622 contract ends in march ....
By the way, SciFi in HD looks great. Saw it at my sister's house Saturday. DVR sucks, though.
