Well, I think most of us aren't going to invest in a new decoder for DTS 96/24 right away, and DTS has really clouded the issue with this new format.
I can't tell you how many fairly educated audio people I spoke to thought that DTS 96/24 would be able to be decoded on current equipment. (myself included) DTS put out vague statements to that effect. I don't really see what the point of another lossy audio format for DVD is anyways? It really won't be used that often, especially since it takes up so much space. I think many of us would just be happy with full bitrate DTS discs instead of having to upgrade our current receivers.
That said, it should be a relatively simple thing to implement in current software decoders. I'm not sure why they haven't done it yet. I'd hook my soundcard up to my discrete inputs just to check it out.
