Yup, the AVS Forum had a huge discussion on this topic a few months ago, and the consensus seemed to be that DTS-HD and Dolby TrueHD decoding capability will be a non-starter because more and more of the discs are getting the "advanced" mastering that does not allow for the DTS-HD/TrueHD bitstream to leave the player. And if the player transcodes the TrueHD or DTS-HD signal to LPCM (which I believe all Blu-ray players sold after October will be required to do), it won't matter much since the audio will remain lossless and output at full resolution. Given the current lack of DTS-HD and TrueHD decoders out there, it will be interesting to see what, if any, differences there are between a natively decoded DTS-HD/TrueHD signal versus a transcoded output decoded in PCM once people can start doing their own comparisons.

The Blu-ray camp has been going with uncompressed PCM for the most part, and even Warner has begun issuing Blu-ray discs with uncompressed PCM audio. But, I am a bit perturbed that some of these lossless tracks get encoded at the lower 48/16 resolution, while some TrueHD tracks on HD-DVDs (which cannot use uncompressed PCM due to disc space limitations) have been encoded at full 96/24 resolution. If disc space becomes an issue, given PCM's inherent inefficiency, then I would hope that Blu-ray producers make more use of TrueHD and/or DTS-HD, since the players themselves are (or will be via firmware updates) capable of transcoding the data into PCM.
