I don't think any of us actually believed the original article, even without that admission a few weeks later (the article you link is nearly a year old) that there was no good source for it. None the less, the future of distribution media is always a matter of interest.
But actually, I know one company specialising in restorations of historical recordings that has almost stopped selling CDs; you can buy mp3s, or flacs (with a cue sheet to make your own CD if you want), or subscribe to streaming downloads, or buy a large hard disk with their whole catalogue, or a section of it (plus an update subscription). But even there CDs are still available at extra cost, and with a delay while they burn them for you.
