Major upgrade in camera resolution ahead due to 8K standard.

I hate to talk like an old curmudgeon, but I think what matters is the quality of the programming, not the resolution at which it is produced. Thus, crap at 8K is the same crap at any lower resolution. Given the lack of quality programming in US television, it would be better not to send it. Thus, resolution is irrelevant to me.
You may hate to talk like a curmudgeon, but you do a good job of it. I don't know what kind of TV service you have, but mine provides me with a wide variety of high quality programming. History channels. Science channels. Military, outdoors, food, DIY, home restoration and remodeling. There's even a National Geographic channel. There is more high quality programming available on TV now then there has ever been.

The digital upscaling that happens on non-4K broadcasts with 4K TVs really works.

That has happened already, in some areas. The music on CD is a big example.

They are already working on 16K TV. It's really just a question of data transfer.

Since the beginning of the home computer age I have always bought one or two generations back from the "latest and greatest". It gives the technology time to settle out so I don't buy a dead end product and it saves a ton of money. When we bought our new TV last year we bought the best of 2015 in the size we wanted and saved almost $1000. I've looked at the newest version at Costco and my old eyes cannot tell the difference. There might be instances where this philosophy doesn't work but I've not found them (okay, my new borescope with fully articulated head might be an exception but I did wait until the price fell below $200).

The video world has been revolutionized in the last 20 years or so. The switch from analog to digital systems was a huge paradigm shift that unleashed lots of engineering potentials.
Rapid innovation will keep going like this for awhile. Panasonic's road plan for 2020 (shown at CES to dealers, back in January, 2017) includes releasing 8K cameras before the Olympics. I have a Lumix GH4, which records 4K. The GH5 records much better 4K, and more varieties of both 4k and 1080P. The GH6 or GH7 will probably do 8K.
There is a diminishing marginal return at some point. 8K makes more sense as a production medium right now. It allows cropping during editing, along with software image stabilization. 4K offers those features now, for those recording and editing 4K footage down to 1080P. 4K theater projection is common. 4K TVs are becoming the norm, and it is getting harder to find decent 1080P sets. 8K will be a standard theatrical distribution medium, then a broadcast medium and home screen viewing medium, sooner than we think. HOWEVER, the sea change of equipment needed to get there will be enormously expensive for theaters, networks, production companies, and local TV stations. There will be the usual chicken and egg dance of who moves first.
At NORMAL viewing distances, 4K monitors, viewed from a 4K source, have only marginal advantages over 1080P. When you get closer, it makes a difference. 8K will allow even closer viewing, although at a distance just far enough away to where you can't see the pixels, you won't be able to see the entire screen!

...Does it really matter for sitcoms and documentaries?
Nope. But 4K production does matter. You can record 4K, crop it or stabilize it in software, and release in 1080P to make a better program. Video and film producers have been doing that for quite a while. 8K will matter first, in the same way. Then 16K will matter that way...

For most of us, it already has. For some, it has to exceed others' bragging rights, though!

Both RED & ARRI, and I think even Black Magic, have made 8K cameras for awhile now. I even saw a 12K TV on display at the Samsung booth at CES. The Nikon D850 is the first full frame DSLR to do 4K video using the full sensor rather than a cropped portion of it. And it will do 8K stop motion time lapse video.
The future keeps coming at us every day. As someone once said, "You ain't seen nothing yet baby!"

The Panasonic Lumix GH5, released in April, 2017, also uses the full width of the sensor to record 4K. It can use its *entire* 4/3 sensor to record anamorphic video, with the right lenses. It also records 10-bit, 4:2:2 onboard.

The infrastructure will be the limiting factor. 8K will be a theatrical projection medium and a production medium well before it is ready for common broadcasting.
