It's likely to do with licensing issues, as the makers will wnat to make as much revenue as possible by selling it to other TV stations around the globe; releasing a DVD into shops would undermine that to some extent.

Also, they may release this on next generation video disk, since it's captured in HD, which might have something to do with it.

Oh yeah of course blu-ray DVD, but didnt they start filming this 5 years ago ?

Did they have HD capture then ?

MUSE

Main article: Multiple sub-nyquist sampling Encoding

Japan has the earliest working HDTV system still in use, with design efforts going back to 1979. Japan began broadcasting analog HDTV signals in the early 1990s using an interlaced resolution of 1035 lines (1035i). The Japanese MUSE system, developed by NHK Science and Technical Research Laboratories (STRL) in the 1980s, employed filtering tricks to reduce the original source signal to decrease bandwidth utilization.
[edit]

MUSE in Operation

* In the typical setup, three picture elements on a line were actually derived from three separate scans. Moving images were thus blurred in a manner similar to using 16mm movie film for HDTV projection.
* Stationary images were transmitted at full resolution.
* Whole-camera pans would result in a loss of 50% of horizontal resolution.
* Considering the technological limitations of the time, MUSE was a very cleverly-designed analog system.
* MUSE had a bit-reduced stereo audio transmission system that was notable in its design as it was not psychoacoustical like Musicam.

Though Japan has since switched to a digital HDTV system based on ISDB, the original MUSE-based BS Satellite channel 9 (NHK BS Hi-vision) is still being broadcast. It broadcasts the same programs as BS-digital channel 103, but will end sometime in 2007.

HD is around longer than that since most cinematic film cameras record in high resolutions that would transfer to video/TV pretty well. It's only the actual broadcast/playback and displaying of a digital HD signal that is relatively new.


PS; also from that same wiki article

For shame.

since when have they been looking to HDTV on a DTT network in this country

I think that's taken out of context...
original quote reads:

"Likely" of course meaning by 2015
