Alright, we have to admit that the format was confusing and was difficult for stores to sell because no one knew what they were, and people wanted MP3 in their iPods instead of HiRez in their houses. That being said....
What happened to the DVD-A Forum, or whomever those folks were. They seemed to cave into the whole DualDisc thing, but half-assed. They never came through with over 100 announced (in various bits and pieces) titles projected to come out. They wasted some effort on the even more insane MVI discs (remember those?).
The whole thing just sort of went away. No formal announcement, no "let's go down without a fight". It was just, OK - no more stream of releases. If you look at the QQ DVD-A release list, you can almost see where it all goes down. By early 2006, the only stuff that came out was stuff in the can, although there were a few surprises left (Love, Perception). And then there's the case of the Bjork box that was set for DVD-A, then went DVD-V.
It's almost like the hose was pulled off the faucet, some stuff drained out of the hose, and that was it.....and almost no one noticed!
At least the end of HD-DVD got a press release!
