In all likelihood, if they do completely abandon Fiber, rather than finding another way to provide the service that doesn't require digging, they'll sell it off to another ISP (I think TFA mentioned CenturyLink). Their DVR was (is?) based on SageTV's product, which I ran at home and found to be excellent (the extent to which it differs from their original product may change my mind on that assertion, though).
[0] I had a problem with my DSL service at my family's home up north that required sending out a tech on 13 different occasions, which required me to drive two hours up north to meet him. I went through four different DSL modems (none of which were broken, but they were basically throwing darts at a wall with a blindfold on). They'd show up, find nothing wrong (on one occasion they offered to replace my interior wiring and decided against it when they discovered I ripped it all out and replaced it with one proper cable run using better cable than they'd install ... and the readings from their test equipment indicated the wire was very clean). They never actually fixed the problem as a result of a service call, it just went away at some point last year.
