I pray that the studio goes light on the DNR for this one...
Oh, and I noticed that when TheDigitalBits first ran the story for this release, the info they posted (taken directly from the press release) claimed that this would be the first time the original Australian audio track would be available in the US, despite the fact that the R1 SE DVD I've had for years definitely has the original Australian audio.
Speaking of which, the specs you listed seem to indicate that the American dub will be the default audio on this release. I hope that's not the case ...
