Ricoh has 4k on the Theta now, which, like with smart phone cameras, may well be easier on small devices. I imagine that Pentax products will be playing catchup until the necessary hardware is priced to make it economic for a small player.
I've been in broadcasting for over 40 years - much of it in TV. I can tell you this: While the TV set manufacturers will try to get consumers excited about 8K video, the truth is, it will be much more useful as a production tool and in movie cinemas. I have a 4K UHD set myself and it's great. But image quality isn't a dramatic leap over 1080p - not in the way HD was a leap over the standard-definition TV picture we all grew up with. 8K? On 42-to-70-inch screens? You need more real estate to see a significant difference.
In most cinemas today, a digital projection of a movie is in 4K. And it's fine. Perhaps 8K will be usefully better on screens that large. But I don't see a problem now. Now... in terms of film and TV production, it's a whole 'nother story. 8K will allow directors to crop scenes if they aren't pleased with the framing or composition. They'll be able to experiment with different approaches while actually shooting a scene only once - which keeps production costs down. 8K will be a major advancement in terms of production.
In terms of cameras that consumers can buy, perhaps 8K capability will eventually make it into most of them. But I suspect the only people really using it will be the people who buy cameras like the Panasonic GH5 today - independent filmmakers and the like. And they'll be using very expensive cini lenses on those camera bodies. Can you picture an average oerson trying to shoot, edit and store 8K home videos on their PC? Sure, it'll be possible. But 4K storage is difficult enough already for many. And how about the processing horsepower needed to render those projects. Again, it can be done. But the average schmo probably doesn't want or can't afford the computing tools needed.
