You might see the emergence of "audiophile" download sites, which offer higher resolution downloads--at higher resolution prices, of course. But if they happen, they will be even less significant in the mareketplace than audiophile labels are today
Pabelson, I'm not so sure this prediction is correct, realistic as it may appear. I am told (in UHF mag) that Apple is looking for more bandwidth so as to be able to supply music in its lossless compressed format. Also, I think any price differential between lossy and lossless downloads is not likely to be so great that it turns away most music buyers.
If download sites really want to take the CD's business, all they need is the ability to sell lossless-format music files. My guess is that's where we're going.
As a side note, that would mean the market for CD-only transports will dry up entirely, but makers of outboard DACs with USB inputs will see a sales upswing.
