Got this earlier from Amazon at £20 (did post about it somewhere here)
The R2 release I have seems remarkably similar to the R1 release described by Rewind Compare. In particular the extras are the same, its in widescreen aspect, has audio commentaries and my receiver is getting 5.1 from it (not mentioned on the box though). Also the digipack is inside a snapper box.
Still got it all to watch for the first time. Very much looking forward to it.
