Okay, terrible post title, but try this on for size, from The Digital Bits:
... we've learned that the first wave of catalog titles by legendary filmmaker Akira Kurosawa has just been announced for release on Blu-ray Disc in Japan. Rashomon, Ran, Madadayo and The Quiet Duel are all expected on 2/6/09 in a box set from Jesnet. So how does this relate to Criterion? Well, Criterion owns the U.S. release rights to many of the Kurosawa films, and was involved in the new HD transfers. So it's likely that we'll start to see some of them released on Blu-ray by Criterion here in the States next year as well. Here's the page over at CD Japan where the titles are listed, though keep in mind that the Japanese discs will likely NOT have English subtitles (so you don't want to go importing them unless you're fluent with Japanese - just wait for the eventual U.S. releases).
I was stunned that Ran wasn't in the first wave of Criterion BD releases, but maybe only because they wanted to get that one absolutely immaculate.
