I loved my VIP receivers. But, I watched two 722s just breakdown. Then, I watched my 722k just breakdown. The only VIP receiver that I had that worked from start to end was my VIP 211k. I've had my Hopper 1 for 6+ years and no issue. That's longer than my VIP 722s combined, and only a year shorter when I add in the time with the 722k. I still have my OTA insert for my VIP 722k. It has been sitting in my nightstand draw since early December of 2012.
Also, just for a fun anecdote, when my 722k broke and I switched to the Hopper, everything was expedited and coordinated by DIRT. I'll never say a bad thing about DIRT. Very knowledgeable and friendly.
Therefore, combine that with Dish focusing on the Hopper, and I can see why they are pushing for people to upgrade to the Hopper.
