I will have agree w/ this comment if Dish come out and said that you will give the HD channel if you subscribe to a package that will have the corresponding SD channel (and you have an HD receiver). Then you don't nee the metallic HD packages. DISH may want to have just a package that have those HD channels (i.e. VOOM) that there a not SD channels.
Saying that you get NGHD for "free" is you paid for NGSD, I think is not the right wayt to put this.
I believe this is a dollar issue. It cost DISH more to get NGHD; so they want to make sure that they cover their cost (which I could I agree with it); but I will be interesting as more HD channels comes out that have SD channel on the lower packages, how will DISH will package this then?
