Yes I suggested that the 900 series never be used again and that may be why they switched from numbers to names like the Hopper and Joey. IF I had to name the 922 it would be the Crapper- just like its future - in the crapper.
As for the iptv future, I think that DISH is seeing that and trying to adapt. The google revue unit was the first step towards it, but that has already been pulled from the market. So I see some kind of hybrid sat/ota/iptv box coming down the line for DISH. It maybe too late though. As the prices continue to rise ever year or every two years , using accounting tricks like "Price Freeze" till 2013, more and more people will be cutting the cords. The networks have become useless for original content and seem to be dropping the programming that once defined them like soap operas. They are becoming just like every other cable network showing gabfests, like the ABC the View, the Spew and the Regurgitation . There is no reason to even have them unless you want local news affiliates. With the internet replacing newspapers , and even tv networks for shows, I don't see satellite , ota or even cable growing much longer. In 10 years I see a different tv landscape entirely being the norm.
