SACD/DVD AUDIO is probably going to be dead soon anyways
Truth is, even prominent people in the sound field know both the failure of DVD audio and SACD, most people don't care about being the sound quality of music. If you click this link it is interesting as to read an interview.

"Indeed, the failure of the DVD-A and Super Audio CD formats as well as the carelessness with which most people place speakers in their homes (on the floor, behind a chair, etc., instead of mounted at ear level) and use crappy, ear-damaging earbud headphones attest to general public's insensibility to sound in space and listening in general."
That article was about
Intergrating Sound and Art
Video and Movies play a huge part in sound,mainly because every young guy or gyal out there, would be yeah- I wanna hear this movie in Surround Sound!, as a result 5.1,6.1, and 7.1 speakers are common nowadays but then again HTIB and cubed speakers kinda negate progress. Thing is though there is an interest in surround sound and that drives the market for more so then multi-channel audio and music, which I admire and love myself.
BLU-RAY and HD-DVD will make DVD and SACD obsolete. The only reason sacd and dvd-audio probably came about is becaue of "copy protection". Since BR and HD dvd has copy protection features everyone will probably migrate to those for music.
The Playstation 3 would probably contribute to blu-ray's success. But how many people out there(mass market) are going to have HD tv's with hdmi, the latest receivers and 7 speakers with a subwoofer. Most people and consumers would probably still use the "composite" video/audio output of the blu-ray and hd-dvd and play stereo. The PS2 and xbox already have hdtv output and surround sound. Walk in to your friend's house/most people wound't have that- or if they do its probably cubed speakers.
Hopefully though Multi-Channel Music will come to light, now did artist really win out with copy-protection on dvd-audio and Sacd in terms of sales, Uh No.
When Blu-ray and HD-DVD comes to the computer it will probably be cracked mathematically.
