With the PS3, you will not be able to get the new formats without a receiver or processor that has an HDMI input that can let it get that eight-channel PCM output. The only way to get any of these formats out of a player is either HDMI (the only approved avenue for decoded eight-channel PCM) or multichannel analog outputs; coax and optical digital audio don't have the bandwidth for eight PCM streams, and even if they could handle the bitstreams (which I don't believe they could) there's no way to pass those bitstreams - not even HDMI will be allowed to do so until HDMI 1.3, and no receivers or processors will pack the decoders until then because they'll never see the original bitstreams.

I'm most interested in Dolby TrueHD, since it's using MLP lossless (DTS-HD and DD+ should be cool but are still lossy compression schemes), but don't have any intention of buying hardware in this format war until somebody surrenders. The closest I'll come to that is settling for a PS3 and living with only getting the downmixed DD/DTS via optical. If you want to have access to the new audio formats, you'll need to spring for a dedicated player in the format of your choice or find a receiver or processor with HDMI.
