BOC: Boxed set of all boxed sets?

[Jason Scruton]

Dusting off the BOC Subject header,

On the BOC web page, posted September 29, 2011:

"SONY/Columbia to release BOC Box Set

There will be a "complete box set" of Blue Öyster Cult's recordings
released in 2012. The box set will include two bonus discs and three
unreleased demos. It is unknown whether the recordings will be remastered
or not. Watch here for further news!"

So, we know it has 3 demos. Anyone care to hazard a guess about what'll
fill the rest of the bonus discs?
Do you think Imaginos will be part o' the set?
If official BOC.com is putting out this teaser, is it likely the band has
some level of say about its 'complete' contents?

Enquiring minds want to ask...
Jason.
