Of minor interest is the 2nd "bonus" commentary version of STID (also available via iTunes) is the shifting aspect ratio version, going from Scope to 1.78:1 for the IMAX shot sequences. The bluray versions will be scope only. http://www.hometheat...arkness-itunes/
Not buying this if there's no aspect ratio change. Similarly, I haven't bought MI4 either for the same reason.
