I read reports where it will be 2020-2025 before it starts becoming more popular for HD that is probably not even as clear as this. One of the biggest problems is going to be bandwidth issues. They are going to need great advances in compression and so forth to bring this to our television sets.
There is also a question whether we really need 4k resolution. If you look at percieved resolution vs distance from screen, you find yourself sitting 5-6' away from a 120" screen in order to be able to fully notice the increased resolution. At that close distance you would become totally immersed with the center third of the screen and never see the edges. You would also probably be uncomfortable and even dizzy. Like sitting in the front row at the movies.
We probably could stand a moderate increase in resolution, say to the proposed 1440p standard. I think that manufacturers need to start looking at improved color depth and accurate greens though before spending too much time on resolution.

That is long overdue!
For about ten years now you can find MSNBC on one of the satellites (in the clear) using 4:2:2 (instead of 4:2:0 every consumer video stream uses, from DVD to Blu-ray).
It most likely is delivered to other network (blank commercial spots) and despite being standard definition the improved image quality is immediately noticeable (has to be watched on a PC; consumer STBs can't handle it).
What's also important, video codec pros claim it would be easier to compress these streams despite their significantly higher bitrate since no dithering will be needed.
Alas, this ship has sailed with BD sticking to the old 4:2:0 (and so had HD DVD). I don't think anything will change for the next 10 years or so...

Ultra HD will be used by the movie industry internally, but I do not see it in the consumer arena any time soon. There will be some really high end systems that consumers could get with it, but I do not see it being mainstream for a very long time.
I see the movie industry using it since it could essentially be a good alternative for 70MM film. It would be great for IMAX.
I could see a lot of special events being filmed in UHD, and movies for IMAX.

Sure we have! We've been hearing about it for years. Here are some of the discussion threads we had on this topic in the past few years:
Ultra HD
Is HD getting obsolete real fast?

HDTV no no longer seems good enough
It is being used by the movie industry today. It is cheaper to digital delivery the movie to your local theater from one stream source. It cost a lot to produce films reels and have to deliver them from several sources IE plane delivery truck etc, to your local theater.
The movie industry is using 2k (with some 4k) via satellite delivery to the local theaters.
The source of 4K footage is very very limited.
When talking about Hollywood, according to Lowry, only very few movies on the best film have anything above 2K.
Almost none have anything above 3K. Most don't justify scans above hidef.
Only IMAX (70mm) movies can justify a 4K scan.
Live TV would have to be done with a 4K RED camera to have this much info. How many do?
