the hdmi 1.3 consideration

As you said, Blu-ray and HD DVD don't support Deep Color (or xvYCC). However, I believe that's confined to the formats as movie delivery devices. What about games (I read that some of the PS3 games may be using a greater color space right now), computer use, consumer made video, etc?

Sony will be releasing 2 consumer HD camcorders capable of xvYCC very soon. Play this video back on a compatible display or record the video to DVD/Blu-ray -- with the appropriate software -- to send via an HDMI 1.3 enabled player to a compatible display and you now have a case for the wider color option.

And what about photography? The higher end digital SLR cameras encode at 12-bit. I believe FujiFilm now and a soon to be released Canon digital SLR will encode at 14-bit via RAW capture. HDMI 1.3 allows for >8-bit transmission and by sending this to a compatible display you'll get less artifacts and a greater dynamic range. This would get more use via the computer route, but since the 60GB PS3 -- which has HDMI 1.3 -- has a memory card reader on-board, some of us would like to see how our digital shots really look in 12-bit vs 8-bit when we view them on our display.

What some have suggested is that players with the capable horsepower could do a pseudo wider color conversion. Using the available color space, the additional data could be interpolated for a greater number of gradations between the colors.

I'm not saying that HDMI 1.3 needs to be the first consideration or that it's a must have for source/display purchases. However, some of the capabilities are very interesting and will indeed improve the digital experience in the near future.
