The japanese dub look like it was online as of last year but can't find a current link.
edit: Not that I'd have posted a link if I found one. But it sounds like this kind of discussion is not allowed anyway? Is it within the spirit of the rules to use a downloaded dub for a couple seconds of audio if you own the blu-ray in your own region? Is the spirit of the rules different if you download a japanese guy's rip from last year (and discussed it, without sharing a link) vs. being sent the file from a fellow forum member?
