I see the industry announcing 8k tvs within three years. So they won't even be ready to do 4K ota broadcasting by then?

But you do know that they will offer it in a few years right? I mean the whole electronics industry depends on consumers buying the next big thing. We had black and white tvs in the 50s to middle 60s and then color tv came out in the mid to late 60s. Then we had stereo tv in the mid 80s, followed by progressive 480p on dvd players in the 90s. Vcrs came out in the late 70s with wide acceptance by mid 80s. Then in 99 we got dvrs . Then in early 2000s we got our first HD tvs, followed by mandatory digital transition in 2010. Now we have 4k tv all the rage in the mid teens followed by of course, 8k bringing up the rear. I say early 8k in three years and full on sales of nothing but 8k by mid 2020s. It just follows the pattern of the tv industry.Sorry, but I can't imagine "8K" being of any value whatsoever in the home. I think it a bridge too far, and it will fail worse than 3D in the home and Smell-O-Vision.
But until they sunset DTV, will there be the necessary bandwidth to broadcast it?NBC and CBS do most of their primetime shows in 4K now. There will be 4K content ready when ATSC 3.0 is ready to go.
If we were talking about analog video at UHD resolutions, maybe. Since data is data, there's no reason that an old transmitter won't send the latest and greatest data. The trick is using a data scheme that allows you to pack all that information into the channel bandwidth and that happens back at the station; the transmitter just forwards a bitstream.AFAIK you can't multiplex ATSC 3.0 UHD 4K and HDTV /480i on the same RF TV transmitters and those things ain't cheap at market scale and neither is the electrical current and so on at that scale and they probably can't give away the analog scan line VHF transmitters now in the developed world so that may translate to the ones thay have now since new 1080p TV's are vanishing at scale now .
