I see that there is no HI-RES version of the 2011 remaster
infact, none of the HI-RES stuff is 'new'
1973 4.0 quad (96/24)
1973 2.0 stereo (96/24)
2003 5.1 surround (96/24)

I think they should have done a new 5.1 remaster and a hi-resolution version of the 2011 remaster , both for the 'Immersion' Box-set - to me this seems to have been a major flaw?

is there any info on what has actually been done on these 2011 remasters and what is different?

I love how people get something awesome unexpectedly, then complain about it not being awesome enough.

Seriously. Hey, maybe you'd like it if David, Roger, Nick, and Jon Carin just show up to your house and perform each album for you in your kitchen? Would that be hi-res enough for you?

Good grief. We're getting unreleased tracks, remastering that is nearly as good as the vinyl, and assorted other goodies for people who are into assorted other goodies. Don't look a gift horse in the mouth.
