While it's allowed within the dvd spec to author discs for multichannel only (that is, with downmix to 2 channels forbidden), there are few recordings made that way, since it obviously restricts the usefulness and hence number of sales. Presumably the same thing goes for SACD, since SACD has only recently emerged from a 2-channel existence, and Sony/Philips make every effort to keep compatibility with existing systems.
You certainly shouldn't let that issue keep you from getting into hi-rez.
Best of luck.
