Seeing there is neither a HR51 or a HR61, I would find this skeptical.A home tech told me that the new DVR will be dubbed HR61. It will be 4K and have more tuners and a larger hard drive than the HR51. His info may be pure BS but at least it's something. I would imagine that these features would be expected by all of us here anyway so really nothing revolutionary, just evolutionary.
Your issue is being seen by many people so "elevated to engineering" has little meaning, they know all about it.
What would you do if they decided to stop changing for the HR54 and just the client/RVU if both were on the same TV?
You know more because you are here and maybe other sites, the D* employees only know what they are told about.I gave up with the set up I had. I took out the C61K and I put an extra bedroom HR24 of my 4K TV. Everything works fine, but I don't have 4K anymore. The issue was also elevated and all I get is a "nice" email every month saying that are still working on this know issue and they will keep me advised. If Dish or any cable companies get any 4K stations before the issue is resolved, I'm gone. I'm thinking of leaving anyway because without the 4K I can get Dish and save money. The techs that come out generally know nothing. It's pretty bad when I know more that they do and I really know nothing. I hope new equipment come soon!.
