I went to the NAB show in Las Vegas last year, 3D was everywhere but already the manufacturers were saying in private that it was dead and wasn't going anywhere. Most were talking up 4K and a few were talking about CinemaWide 1080p. With most filmmakers shooting action-type films on RED or equivalent 4K cameras, it's a natural evolution to bring that down to the consumer level. It's already been in use in government applications (NASA, NSA, other TLO's). There were a few displays, and the depth of the picture was very impressive. If I remember correctly it was in Acer's booth that I saw my first 4K display, and it was across from Panasonic showing off their massive 16' 1080p screen. The specs from the HD working group already have 8K laid out and beyond. When talking about 4K and 8K, you have to take into account the RAW image specifications, which may include visual timing details. The RED ONE maximum RAW image size is 4480x2304. If you look closely at a live shoot for almost any television show or movie, on the director's screen you'll see several sets of white box outlines, which cues the director to what will show in 4x3, in 16x9, 21x9 and full frame formats. When people in the industry talk about 4K and 8K they are simply carrying through the lingo from the RAW formats that the material actually gets shot in, not the broadcast standards they will be displayed in, two different things entirely. UHD 4K exists, although broadcast standards have yet to be worked out. We are 4-8 years from 4K being ubiquitous. UHD 8K is being worked on, but anything beyond the experimental (or TLO usage) is probably 20 years away. Today I'd be much more interested in CinemaWideHD, which better captures the cinemawide frame movies, and is fairly compatible with existing production and broadcast standards. Alas, it appears to have been left as a niche product.
