Why not DSD (SACD) audio instead of PCM?

[Manco]

SACD's one-bit word length and very high sampling rates was "theorized" to better reproduce analog. As we can see, SACD never really took off the way it was expected.

There is no sense in requiring BR player manufacturers to invest in PCM -> DSD (SACD) conversion in the players when everyone is so heavily invested in DVD already...which carries PCM. Nearly all BR players will be used for DVD upconversion at the outset and this would just add additional cost. It was a good decision of the BDA to stick with what already works. We are already getting "uncompressed" PCM on many BD's plus the lossless audio codes. I see no reason for DSD.
