Are CD players goig the way of the 8 track,and the cassette?

How do you get really high prices for audio goods? You have a limited supply out there, they aren’t made anymore and huge demand. You know, like cassettes. Hel-loo! Whereas CDs have always been expendable dog meat. They made a million of them.

I feel like many on here that they may struggle and will not be a mass market thing at all in years to come as Record players went as CD came in , having said that i also believe that "high end" High Quality sound reproduction from a small form physical format ...thats CD .. will always have a place as so many millions have been produced ..

I miss my 8 track in the glove compartment of my '67 Camaro convertible... 

Considering that there are hundreds of working 8 track players available on ebay right now,  some listed as new, I think that we will all be able to buy cd players for as long as we live.
