@Rango you put a lot of what I've been thinking about lately in regards to these releases into words—I appreciate the objectivity and effort to see if from multiple sides... that's all I'm trying to do too, just figure out "what
exactly is going on here from a business standpoint?" of course followed by "and what will that then mean for the future of this hobby/these kind of releases?"
But in terms of the question who will buy what, I think we have a relevant case study in the form of the Dark Side of The Moon SDE that just came out. There was a very parallel discussion going on both here and at Hoffman, and I think an even stronger chorus of "this is mainly a retread of the Immersion set and not even as good, except that pearl in the oyster of the Atmos mix."
Dark Side was similar in physical heft and price point, way less appealing in terms of true "new" content (I think pretty easy to argue, this coming from a Floyd completist), and following on the heels of a SDE of the same title (that is arguably better) only 12 years prior. So in a few ways, it maybe had even less going for it.
I myself asked "who is this for?" "Who will buy this?" But whoever they were and for whatever reason, buy it they did. Seemed to sell out and now the official Floyd shop is touting limited additional numbers available... kinda feels like whatever they were hoping to accomplish, they did. Maybe Who's Next isn't exactly on par with Dark Side in the overall zeitgeist, but it's gotta be damn close. Time will tell...
Epilogue: I bought Dark Side 50, kept the Atmos disc to put into my Immersion box, and easily sold the remainder for a great price to a chap who had no interest in the Atmos. Win-win, and my Immersion box feels like it's the best of all worlds now.
Pre-ordered Who's Next too, because it's super important to me—I don't have any of the other Who SDEs and am not really interested. I expect I'll hang onto the lot of it. Was easier to pull the trigger since I had a sizable
gift card balance due to having been sent a fake of the Bowie Five Years box a few weeks ago. Gotta stay vigilant with these things!
