GF has been tearing up our neighborhood this week and last laying cable (I'm in Chapel Hill). AT&T did the same about 6 months back. I was holding out for Google, but this makes me think even when they get it up and running, the support will be nonexistent. So maybe better to go with the devil we know (we already have AT&T U-Verse, just not gigabit). At least they lasted long enough to force AT&T's hand...
I'd still switch to Google Fiber. As someone who spent over a year dealing with what AT&T calls "support"[0], concerns that Google could be any worse would be minimal for me.
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.
