Does anyone have much knowledge on this film on DVD? I'd like to make my mind up whether to buy the R1 Masterworks Edition or the forthcoming R2 Special Edition - 2 discs. I'm tempted by the R2 with the documentary, but priority is the picture. Obviously one isn't relased yet but does anyone know about the transfer/picture quality? That said, the R1 seems to have Japanese audio in 5.1 whereas the R2 is stereo. Thanks.
