These editions are also being heavily touted as the 107 minute uncut version, as the Japanese theatrical release was cut by some twelve minutes. The Blu-ray is advertised as featuring English audio, but only in standard Dolby Digital Mono. Both editions have Italian as their main tracks, with the BD in DTS-HD Master Audio 2.0, but only with Japanese subtitles.
Here's the Amazon.jp listing for the Blu-ray with a pre-order price of about $37 USD. The picture format on the listing incorrectly states 1.78:1, which I'm assuming is a mistake like many new Amazon listings tend to be. Eclipse's BD/DVD trailer is seen below (in the film's correct aspect ratio).
