fbourgoin,

You still haven't answered the question. How will this disc be playable on ANY of the SACD only players on the market? Those players will not have the firmware or perhaps circuitry path to do it.

Plus, I'm still not sure that this will even be playable on a combo SACD/DVD-A player. Logically speaking, it would have to register both as either a hybrid SACD/VCD (for video) disc or a hybrid SACD/quasi CD/DVD-V disc. But it would have to function as a true CD disc (I believe) for an SACD player to be happy with it. That is a tall order.

This was just a marketing announcement more than a product announcement anyway, so it remains to be how well things go. Let's not hype (or spell doom for others) a product that you can't buy today or at date certain in the future.

Lastly, again, why would Sony back this venture and forgot the licensing revenue from their own SACD2 format? Remember, this is an exercise in licensing as well as selling discs. Sony is unlikely to pass that up. Expiring Redbook CD licensing is what spurred the development of SACD in the first place.
