I have read that at least one vendor (Sony?) was planning on 
delivering an LED-based rear-projector with more than the traditional 
RGB.  This is likely easier to do using LED-based rear-projectors than 
with any other current technology.  With today's use of ASICs, FPGAs, 
and DSPs, support for more primary colors in consumer devices becomes 
quite feasable.

Regardless, when wide-gamut is introduced, it is an appropriate time 
to ditch the long legacy of CRT-based video technology.  Today's 
products are emulating a 67 year old CRT-based delivery chain which 
will not exist at all in a few more years.  Let's follow DCI's lead 
and describe colors in a device-independent manner which is also 
designed to make best use of available bits.

In the mean time, display vendors should strive to meet already 
established standards rather than differentiating themselves based on 
how they can creatively corrupt the image.
