Exactly. Because when you do those sorts of "cut-over" transitions, everyone with the old gear is immediately left out in the cold. I suppose they could setup new UHD channels that broadcast at the same time as the old HD channels. But then that's sitting on extra spectrum unnecessarily.
I don't think we'll see ATSC3, or whatever, for a good decade from now.
Blu-ray discs also have a similar "cut over" problem to the new 4k format. I fully expect all future physical formats to be stillborn, but for different reasons than the "cut over" problem.
Ultimately, streaming is the best option for integrating the latest tech. When your piece of equipment (Apple TV, smart TV, or whatever) connects to a service like Netflix, they can do the protocol negotiation thing and send the highest quality format that both the client and the server supports.
At the end of the day though, I don't perceive much of a difference between 1920x1080 and 3840x2160 unless I'm really close to the TV set. I don't see this resolution improvement as a "must have" upgrade unless you have a really
large TV, or you sit really
close to it.
The main thing that I'm looking forward to in future formats are: eliminating interlaced video, 10 bit color, and higher frame rates. If we could get 1920x1080, progressive scanned @ 60fps with 10 bit color, I think that would be sufficient for most scenarios.
