Unless you mean Dolby Digital TrueHD (which is an evolution of MLP) and DTS-HD.
HDMI is primarily for transmission for video with audio tacked on. Correct me if I am wrong, but I don't think you can send audio only on HDMI (unless you pad it out with a blank video signal).
The new lossless formats from Dolby and DTS are intended to be used for audio soundtracks accompanying an HD video stream. The intention is so we can finally hear a movie's soundtrack lossless - a big win, in my opinion.
I don't think at this stage anyone is seriously working on using these formats for an audio only disc format. Given the state of SA-CD and DVD-A, I don't think there is a market for it.
Why would anyone want a Bluray or HDDVD disc with only audio? All that extra disc capacity would be wasted, given that you can already store 1 hour of *uncompressed* Linear PCM at 192kHz 24-bit 2ch on a DVD5 (and double that on a DVD9)? Double that again if you apply a lossless compression algorithm (like MLP).
Already we are starting to see BluRay and HDDVD discs with uncompressed LPCM 5.1 audio tracks. I think in the future we will see more discs with lossless audio tracks - particular concert performances etc. That would be good. But I think it's unlikely we will see audio only titles.
PS - If you have been deliberately avoiding HD, don't. We having been watching HD over the air ever since 2001, and basically once you get used to HD, DVD/SD just isn't good enough anymore. We have virtually stopped buying new DVDs apart from the occasional special interest title.
