I'm seeing a lot of comments concerning joy over the release of a single disc Blu-Ray edition outside of the box set, and I certainly echo those sentiments, especially since the Blu-Ray edition will be out before the box set.
However, I don't anticipate that this release will set any sort of new standard for other Pink Floyd albums as Blu-Ray only releases, mainly because this release is an audio-only release of the main album. (i.e. There's no bonus tracks, live audio, video footage, etc. to flesh the album out for a truly deluxe edition, the way they can with other classic Pink Floyd albums from the era.)
Anyway, my plan is get to all three editions (Blu-Ray, SACD, and Box Set). However, the SACD will probably remain sealed as a collectors item.
