I'm thinking that without another mandate, 3.0 will be a slow turtle dragging its feet in adoption. The problem is that there are too many alternatives now and so many people would rather stream their entertainment to their phone or tablet than to "tune in" a channel. Don't get me wrong, I don't like government interference, but I'm saying there is too much competition out there in the market for alternatives to simply tuning in to see a local TV station. What pushed the last mandate was the need to clear up the airwaves for the cell phone companies and make more efficient use of the bandwidth. If the FCC had mandated 3.0 adoption with the last repack, we would probably see more progress, but with the bandwidth crunch, younger viewers wanting to just "stream" content, and stations not wanting to spend out the extra money on transitioning equipment without seeing a big perk in revenue, it's probably going to be a slow adoption at this point. I would say that OTA viewing is sort of a niche thing now. I just purchased an HDHomerun 3.0 tuner to simplify my setup and put everything on the network. The picture quality on 3.0 does look great due to the better compression and fewer compression artifacts seen on 1.0, but nobody's racing to put 4K OTA. The best you can hope for now with 3.0 is HDR and 1080p with little to no macro-blocking.
