The BDA website has just been completed and if you go here you can download the specifications for Blu-ray. Besides the already announced additions of VC-1 and MPEG-4 AVC HP there is also the surprising news that DTS++ will be one of the mandatory audio codecs. DTS++ can go up to 7.1 channels with 24 bits and 192 kHz sampling. Currently the BDA is still deciding on the maximum bit rate for DTS++. BD-ROM will support 1080p at 24 fps, but currently does not support 1080p at 30 fps (or 25 fps). I know that most Japanese companies are big supporters of interlace but not including 480p at any frame rate and not including 1080p at 30/25 fps seems a pretty odd decision. Hopefully this will be corrected before the BD-ROM 1.0 specification is made. Also the supported video formats for VC-1 have not yet been finalized.
