I think the death of the CD will signal the upcoming death of the big record labels or will at least reduce their power and influence to almost nil. Their power lay in controlling access to CD distribution and promotion. Their industry connections and money controlled who received airplay but that's now being undermined by band owned websites and online retailers' providing free samples of tracks and sometimes whole songs for free.
What has to happen is that a proprietary lossless standard needs to be adopted by the entire industry so that playback is assures on every home media player, computer, receiver, Blu-Ray player and portable device. For now we have AAC vs MP3 on the lossy side and FLAC is getting there on the lossless side buy it's not quite universal. A replacement for CD, a format that who's 16/44.1 format was intended as a convenient to use WAF friendly mid-fi compromise between storage & processing limitations and cost, is long overdue. It's why I'm buying better than CD 24bit high sample-rate audio whenever possible and yes I'd love to see Amazon bring down the price of 24bit FLACs.
As I have stated before, downloads for classical music have in the main a long way to go before they are ready for general application.
We need a Red Book standard for downloads , like the CD, or insist on a perfect CD image for download.
Lossy formats do not cut it in the classical realm.
The big issue is that the CD must play without clicks and pops between movements etc.
Also within movements you need track markers that play in a seamlessly without any break or artifact. In other words it must have all the attributes of a CD. You must easily be able to navigate the program.
There are some sites that you can download a perfect CD image from, with the cue file functioning perfectly.
There is no cue file for data type downloads. Since there is no Red Book for high def. downloads this remains a big problem as high def, recordings have to be downloaded as data discs, which is very unsatisfactory.
I don't download much music, as it is a real pain. Far more often than not I have to totally remaster the contents. This is a lot of work. It is not infrequent that there are problems that can not be corrected in remastering, because of missing data.
So I don't see CDs going away in the classical arena until these severe shortcomings are fully and completely addressed.
