suround SACD availability

The current Stereophile reviewed the Sony 555 multichannel SACD player, and I recall that there's also a Phillips multichannel SACD player. What's the situation on availability of MULTICHANNEL SACD software?
It's out there. More daily. Miniscule compared to the music selections on CD but, hey, it's a new medium.
There are about 40 available with lots more due by Xmas. The new format is quite an expereince.
