New customers still get the 722, there has been nothing said that denotes the new LNB will not work with VIP equipment or below, RVers can still use if it works with VIP equipment and below.
The 722s in stock are not just for replacement. New customers get them and 211 and even 625's. They still offer them, but do not still manufacturer them, eliminating that from your point. The only thing that would make sense would be commercial accounts, and with the number they would have in stock(I promise, they have a great many in stock) the DPP LNBF can be phased out. Now if someone came on here and said it will not work with VIP equipment, then you may have a point, but there has been nothing proven to that as of yet. Both your argument and mine is all speculative, and unfortusntely there are not enough facts on the table yet. We do not even know what the new LNbs can do yet. For all we know, it can handle Commercial accounts with the right improved equipment there as well.
Well it already can't work with *all* DPP equipment since it only has two outputs. You couldn't hook it up to a DPP switch. And given the documentation we've already seen, it's fairly obvious that the way this new LNB works is by cramming all of the circuitry of a Duo Node into the LNB. Now, it is possible for it to default to "DPP mode" until it sees some signal from a Hopper, but that seems unlikely given the fact that they still need DPP out there for all of the other reasons I said.
It's possible for them to refurbish 722s and keep reusing them, and of course they'll keep selling them and leasing them as long as they have stock. It's not like they're going to throw them away. Receivers have much more turnover than LNBs, though, and you don't send LNBs back when you cancel service or when you upgrade. There won't be a huge fleet of LNBs coming back to Dish over time. They'll need new ones as time goes on and new installs are done.
I wonder how you hook up a 2 hopper 2 Joey 2 VIP 211 setup?
How does a DPP44 connect to this?
It doesn't. You'll need to use a legacy DPP LNB with the DPP switch.
