While DVD-A makes the most marketing sense for equipment manufacturers, SACD makes the most marketing sense for record companies. Historically speaking, the record companies have always wound up setting the standards, not the electronics industry.
Incidentally, HDCD has by no means failed and a lot of new CDs have come out in that format. There is also nothing to stop the red book layer on a SACD from being done using HDCD.
