Really? Vinyl pretty much died out and came back to life because people were nostalgic, either for the qualities of the audio (which is typically terrible) or because some music was never made available in more modern formats. Most of all, I suspect that some people started picking up vinyl when prices hit rock bottom, because no one wanted it at one point, which evolved into the fashionable trend that we see today.

I'm pretty sure that you're going to run into the same thing with CD's. You're going to have some people nostalgic about it and others raving about the quality of uncompressed audio (even though few, if any, people can hear the difference). But, most of all, I suspect that some people will start picking up CDs when prices hit rock bottom and then it will evolve into another fashionable trend.

If books are ever killed off by ebooks, which I doubt, we'll see the same thing there.

I'm fairly confident in these predictions too, since we see it happen over and over again. They're called collectables.
