Stacey,
I think I have heard as much as any thus far....but, always happy to hear more if I've missed something.
No, it wouldn't be the original 4 channel quad mix (albeit that is the one that has apparantly been seen at some hi-fi shows on DVD-A), but, a new 5.1 mix instead....therefore, I agree, not the original as such. It will still of course be from the orignal multi-track tapes. Very much how all re-worked DVD-A like LA Woman and Rumours were done I guess.
I also read that Sony have engaged the band but not Alan Parsons (the original engineer). Yes, he's probably not too happy. He was stated as still having lots of ideas for it.
I don't know if it is the Waters or Gilmour side of the band but don't expect it to be both together. Who it may be 'approved' by (or not) I'm not sure. If some of the band was involved, I'd hope that was enough.
Anyway, if it does reach DVD-A, then let's all enjoy. If it's just a SACD, then some will enjoy....but not all.
I agree with Harbor53's point in that it would be a real showcase disc. Like many BIG movies, that you just have to put on when your mates come round.."right have a look at this then" ...I get a buzz from their reactions, and therefore, some degree of satisfaction for all the extensive investments in M.
Rgds
