Gord, since it's extremely unlikely that human hearing capabilities will miraculously improve in the future so as to make the CD 44.1/16 specs become inadequate, I expect to continue enjoying(in surround)the excellence of the present CDs I have and to purchase new ones.
You appear to have an impression that DTS-HD MA is some uniform high definition standard. In fact, if you examine The Bluray stats
here (select DTS-HD MA in the Audio box and then Filter), you'll see from the summary table at the bottom that most of the discs have no special HD characteristics(other than the label). Generally the audio is 48/16, similar to the CD's 44.1/16.
