SACD/DVD-A and 2-channel recordings


I had wondered if it would ever be the case that only multichannel recordings would come out leaving us 2 channelers in the dust. I was told by a dealer friend of mine that Sony professed to always include a remastered 2-channel SACD layer with every SACD whether it is multichannel or not.

I am wondering if anyone else has heard this and whether this is also the case for DVD-A?

Thanks,

I am fairly sure it is in the specs, (what are they calling it, scarletbook?) that all SACDs are required to have a 2 channel mix. The multichannel and hybrid are optional.

I don't know of any DVD-A that include 2 channel mixes, but then again, I dont own any.
I might have been a little sloppy in my language use when I used the term "layer" instead of "mix". It appears that atleast for SACD's, there will always be a newly mixed 2 channel SACD version even when there is also a multichannel version.

Thanks all,
It's been my experience that ALL SACD discs have a dedicated 2-channel SACD layer (not mix but layer). This is true even where an SACD may have an additional multi-channel SACD layer and/or CD (redbook) layer.
