Specs at WHV Japan are up at this link. The domestic Japanese version of the set, which is out November 12th, should be identical to the USA and other editions. WHV Japan usually have highly accurate specs, but, as a rule, they only detail original language (i.e. English) and Japanese options.
Again, as a rule, Japan gets the same discs from Warner that the USA (and usually, everywhere else) does, but Japanese audio and subtitles are only available when the Disc Menu language is set to Japanese on your Blu-ray player. So those outside Japan almost never see them, and don't know that they are there. On the other hand, when you access this Japanese "version" (it's actually a playlist), you will get Japanese menu screens with only English and Japanese options, and any other Western (and other Asian) dubs and subtitles will not be available.
Unfortunately, I hope that for once, WHV Japan is wrong.
Video: 16x9 Full Frame (1.78:1) Note: 4:3 Material is specified 4:3, like this, or this, out the same month.
Audio: English: Dolby Digital 5.1 (no lossless) but there will also be a Japanese: Dolby Digital Mono track.
Subtitles: In addition to English SDH, (and the French, German, Italian, Latin Spanish subtitles already specified) there will be Japanese subtitles, as well.
Discs 1, 2, 4, 5, 7, 8, 10 and 11 all have 264 minutes of content. Disc 3 has 220 minutes. Discs 6 and 9 have 132 minutes, and Disc 12 has 44 minutes.
Disc 13, the bonus disc, has 155 minutes of content.
Discs 6, 9 and 12 are single-layered BD-25s.
Even if I weren't concerned about compression (WHY are there any BD-25s in here, anyway?!), the lack of lossless mono (or at least 5.1, if you must) is unacceptable. Let's not mention the 1.78:1 spec, which should be outright incorrect, based on information we were told before.
In case any of it changes, here is the relevant info I am seeing at WHV Japan, also translated via Google. Remember, only the English and Japanese options are specified:
