It looks like all Dish receivers will soon be HD only receivers, going forward. From the same uplink report:

I am guessing that Dish is sending this message to everyone still using the really old SD-only receivers. (The fact that the message specifically points out "HD viewing" is a big clue.) Based on the "500 hours of DVR space" it looks like Dish is trying to migrate everyone to a Hopper Duo. For those with non-DVR two-TV receivers, such as a 322, Dish may offer them a DVR-disabled Hopper Duo plus a Joey. I have had (quite by accident) Dish disable the DVR functionality on my Hopper Duo and remove the DVR fee, so I know that it can be done.
