My own opinion is that it is a pity that marketing cycles are being 
burnt on this right now at a time when there are still so many 
problems with existing display technology.  Many displays still can't 
even get their primaries correct, and all consumer devices are still 8 
bits or less of signal information combined with lossy compression. 
Black levels are still unacceptable. A fellow named Dave Corbitt 
listed many of these issues in a prior email.

While one might assume that film will be the target of wide-gammut, it 
seems to me that digital cinema and home theater (i.e. off of HD-DVD 
or Blu-Ray disk) are most likely to benefit from wide gammut.  Cineon 
log - based film production already supports wide-gammut, even if the 
colorist is not able to see it on his display and the colors are a bit 
inaccurate.

Digital cinema has far more per-device dollars and bits to play with 
than home theater, but marketeers are more likely to tweak home 
theater first since it is easy to do so and the consumer does not know 
any better.

Let's get Rec.709 reproduction perfect before we start worrying about 
making the problem even harder.
