Agree with your analysis and prognosis.
It was ALWAYS all about copy protection with "better than CD" SQ used as an incentive to get equipment makers to sign up for CP'd digital audio. The plan fell apart when a cheap standard digital interface was not supplied to the equipment makers along with the software. By the time iLink was deployed, it was too late - digital video was coming down the pike and digital hi-rez was shoved off to the side to grab what bits it could in the new interface. The HDMI inteface is the result.
It was always going to be a single digital inteface for both video and audio, but I believe it was theoretically possible, in the early days, for hi-rez audio to prove out the validity of jitter-free buffered transmission modes such as iLink's HATS. Had it done so, hi-rez audio would certainly have claimed HDMI interface real estate for buffer commands. Instead, the fight for jitter-free audio bits will have to be waged all over again.
Chris points out that we have, in HDMI, a very large pipe for the transmission of unlimited audio quantity and quality. The specific form of software transiting the interface is irrelevant as long as hi-rez SQ requirements are met. Sure, we'll all have to rebuy our software, but after LP, 8-track, cassette, DAT, CD, SACD, DVD-A, etc., we've demonstrated we're up for that.
