I don't think cds will disappear anytime soon but they will become harder to find as I suspect eventually only the well known bands will release in cd form....who would have thought that vinyl would still be around after all these years...the majority of people on this forum, many who avidly collect cds, don't bother with vinyl and yet we still see vinyl releases...I expect that I will have to bite the bullet and start picking up releases in digital form in a few years as that will be the only way to get the music I want but it will be a sad day for me...
