But the 222 & k (especially the non-k) were never really meant to be DVRs, so it's not really a fair comparison, who else puts sata ports on their non-DVR boxes?
Bandwidth may have been an issue, but they probably could have addressed that somehow, or limited the DVR functionality to the K. More likeley it came down to a marketing decision as much as anything else.
The 211 makes marketing sense. For the very price conscious 211 only users, you get an extra $40 up front, and I bet end up moving some of them to a 722 or 612 once they realize how nice it would be to watch one show and record another. For account with a 211 as a second or third receivers you get the the $40 and make the account little more sticky.
A DVR enabled 222 is hard to fit into the pricing model. You end up with a box functionally equivalent to a 722 - do you undercut the 722 by not charging a DVR fee? If you charge the DVR fee, then what's the point?
Dish was VERY CLEAR from day 1 that these 222's were designed to be DVR units using external HDD, as well as non-DVR units, and that such feature was coming. They affirmed this a few more times as time went on, and even Ergan was telling us on the Tailgate Charlie Chat how the 222's were going to be just like the 211's and all they had to do was send a firmware update and we could all record using an external HDD. Such a feature could also SAVE Dish money as having to replace otherwise perfectly good boxes just because the HDD is bad is VERY expensive and accounts for a big part of his 2 (last I knew) massive equipment return and repair centers. You get the box, and you pay for the HDD and you pay to replace it. If that does not bring in enough money, Charlie can always increase or invent a new fee, just as he jacked us all up with the current fee structure.
I think that so much time has passed since the intent of the 222's being external HDD DVR's, that now the focus is on whole home DVR set-ups, and any money on R&D is best spent getting HDTV in many rooms of the house and really focusing on that as the primary competitive technology, just like so much time has passed since the inception of the Sling Extender, it is now anachronistic compared to the XiP technology. I just wish Dish would confirm that the 222/K DVR feature is dead, like the Sling Extender, so we can move on from there, as well. But, honestly, I have already made up my mind that they killed it a long time ago, anyway.
