Pink Floyd Immersion Box Sets

Hi all,
 
Just saw the new Immersion box sets on Amazon, which look spectacular - assume they will sound the same.
 
They are reissuing The Dark Side Of The Moon, The Wall, Wish You Were Here, etc.  As part of each box, they appear to be delivered in DVD-A and BluRay formats as well.  For example, Disc 3 alone features the following:
 
DISC 3 – DVD 1, ALL AUDIO:
 
- The Dark Side Of The Moon, James Guthrie 2003 5.1 Surround Mix (previously released only on SACD) in standard resolution audio at 448 kbps
