At that point, 4K for home video simply won't be enough...since that's only about half of what film can hold and it's less than what you can at the theatres.
So now us home video enthusiasts will have to go through several format changes (starting with Blu-ray) before we ultimately end up at 8K.
The thing I can't stand is the current HDTV format really has not even fully switched over just yet. There are those who still have 4:3 TVs and some who have HDTVs and don't yet have HD sources or only tune into the SD channels.
Many current HDTV broadcasters limit the available bandwidth and many current Blu-ray releases don't even get proper scans (or film materials,) or utilize the highest (best) quality audio format.
There was talk of HDTV standards (an improvement over NTSC) since the 70s...however it took about 25 years of working on a standard...and adopting one of them in the United States till we even had our first HDTV broadcast around February 19th 2009.
The talk of 4K is all nice and sweet. However, I can see it now...in the mix of releases there will be upconverted 2K material, digitally filtered grain from filmed sources to help give the look of digital cinema...and audio limited to compressed Dolby Digital. In the end, maybe it won't matter...since by the time there are standards for 4K and actual product released...there will be a whole generation or two who grew up only watching digitally recorded, digitally projected movies.
Before moving ahead, everything currently wrong with Blu-ray need to be worked on. Such as Blu-rays being released with compressed audio soundtracks...filtering applied where it has no business in the first place, using digital "masters" that were intended for older formats and a whole host of other misuses.
Blu-ray when done right is gorgeous. However, those are the exceptions. When outstanding Blu-ray releases start becoming standard and we get used to it's quality...I would think at that time is when people might really want to start upgrading to something even more outstanding when compared to Blu-ray.
Right now I see 4K home video as a solution to a so called problem named Blu-ray. However if we don't learn our lessons with our current outstanding format (Blu-ray,) we will again be setting ourselves up for more disappointments.
