Most Dylan fans are complaining about the price. If you don't believe me, go over to the Hoffman board and read the 100+ page thread on this release.
It's hard to say if a BB release like this would do well. I don't think it would considering they've released session boxes behind their two most popular albums already. If they did a release like this of Friends I'd buy it in a heartbeat but I don't think many people other than board members here would be into it. I do think the BBs could release a multiple cd box set of live shows that would sell well. Either a collection of full live performances from '65 - 95 or a multiple show collection from the '73 "In Concert" recordings.
The reason the Dylan release works is because the '65 - 66 period covers material from three great albums (Bringing It All Back Home, Highway 61 Revisited and Blonde On Blonde) AND he recorded live in the studio including vocals. So if you have 6 versions of "I Want You", you have 6 different performances of "I Want You" usually with Dylan trying different arrangements, tempo changes, etc. on the song. It's not your typical, "let's try this again but have the bass come in earlier" or "let's try this again with the drums not so loud", etc.
