I think your question would be better debated by those who do not have a substantial collection of CD's, but if you're like most audiophiles you may have hundreds of CD's. They are not going to go bad or degrade in sound quality if properly taken care of; any equipment you buy will always have the software. The only question would be if CD playback gear will be supported in the future. I don't see why they wouldn't for the very fact that CD's are practically in everyone's home.
Or look at it this way - 20 years ago when CD's came out and promised great sound 4ever, there was the question of whether LP's would be around in 2008.
