What I'm saying is --- --- Sony isn't characterizing anything as "compliant with Wave"; --- Sony is talking about compliance with version 1.1b of the TCG specification; and --- Sony is saying (separately) that Wave's software comes with its platform.
I guess this means I disagree with you about "less of a commitment," because I don't think Sony is saying "Wave's stuff will work if you want to go out and get it." I think what Sony is saying is --- --- its platform has a TPM; --- the TPM is compliant with version 1.1b of the TCG specification; and --- Wave's software comes in the box.
