The only Blu-Ray player likely to omit built-in Dolby Digital Plus and DTS-HD decodes is the Playstation 3. Standalone players are going to have to include built-in decoders with 7.1 analog outputs much like early DVD players included built-in Dolby Digital decoders because of the large installed base of receivers and processors with no way to handle the decoding internally. In fact, the need for it is even greater now because the installed base of home theaters has grown drastically since DVD was launched in '97.
