From High-Def Digest:
After months of rumors and anticipation, Warner has officially announced an early-December bow for dual Blu-ray versions of 'The Dark Knight,' which will hit high-def as the studio's first BD-Live release.
In what could be one of the biggest-selling Blu-rays of all time, Warner will unleash the worldwide global box office phenomenon on Blu-ray in standard two-disc and collectible limited edition versions on December 9 (day-and-date with the DVD).
Tech specs for the standard version include the 153-minute feature film spread across a BD-50 dual-layer disc with 1080p/VC-1 video (2.40:1) and English Dolby TrueHD 5.1 Surround audio. (Dolby Digital 5.1 Surround dubs and subtitles are also provided in English, French-Quebec and Spanish.)
