Will SA-CD and/or DVD-Audio be superseded by Blu-ray Disc or HD-DVD?
No, that isn’t likely to happen. Blu-ray Disc (BD) and HD-DVD are aimed quite squarely at storage of (high-definition) video and secondly on data storage for computers. No audio-only variant of BD has been specified, and as far as we know DSD hasn’t been included in the range of optional audio formats on BD. You may consider SA-CD to be the HD Audio complement to BD. Both formats work with newer versions of the multichannel audio standards by Dolby and DTS: Dolby TrueHD and DTS-HD offering up to 7.1 channels of audio. Like Dolby Digital and DTS however, these audio formats are primarily designed for use with movies.
