Madman/Eastern Eye in Australia (R4, PAL) are putting out pert' near all the G-films, including the Heisei releases Sony put out dubbed and/or pan & scanned years ago. Their's will be widescreen/anamorphic with the orig. Japanese and English subs. Alas, they do not have King Kong vs. G, but it is of course available from Toho on their R2 disc.
