Also, check out the Neil Young blueray boxset, part 1 comes on 10 discs and contains virtually everything from 1963-1972 in 192/24 plus loads of extras, the price and scope means it is meant for fans - but trust Mr Young to point the way to the future... I hope he sells a few because I would love to see other artists & bands try this kind of thing.
One of the main sticking points for Blueray Audio is the classic loop
Expensive Price=Poor Sales=Costly Production=Expensive Price=Poor Sales etc etc.
Difficult to say how the end consumer can affect any real change, other than to buy Blueray Audio discs when you see them. Remember, many publishers have had their fingers burnt with high-def audio (remember HD-DVD). You can see the problem Blueray Audio is sandwiched between DVD-Audio, SACD and Digital Downloads from the likes of Linn etc. Any market so fractured seems likely to remain a niche market, TBH.
