The production sounds good, but I just don't see Blu-Ray becoming a viable high res audio contender anytime (it is a Sony format after all ). And I believe The Fragile was recorded all digital as well, but my vinyl sounds better than the CD.
I don't regret buying the ultra-edition, I can sell it later on if I wanted to. And the fact that it sold out so quickly and wasn't shipped to dealers (that try and make huge profits when items go OOP), I think I'll be able to get back a bit more than what I paid.
