The big interesting news is the hi-res release. That would indicate new work being done...unless the 2004 CDs which were merely a repackaging of the loud 1997 discs did indeed have some DSD processing going on for an abandoned SACD release.
Still, the hi-res files could be without loudness which would make for the best official versions of the non-LP material that's been released...
No mention of any additional material other than bonus interviews. And of course there's the now-obligatory overpriced vinyl boxset aimed at hipsters.
