I seriously doubt it. Even the vinyl thing I think is more driven by fad then nostalgia. I.e. few over 40s - even audiophiles - seem to me that enthusiastic about vinyl, whereas some 20-40s who like the limited edition / collector aspect of the media and also find the hardware cool to look at are probably the growth factor. I could see the novelty wearing thin as they get older with more obligations (work and mostly children). With that kind of life / day, who wants to come home and hassle with a record player?
CDs on the other hand are for the most part not rare and most all CD players don't have the "cool" factor, with a few exceptions. They are also not nearly as convenient as digital files on phones / computers / etc. Once car stereos, perhaps the last cd hold out, start integrating Bluetooth, AirPlay, etc for easy wireless communication, I could see them dropping cd all together. Already many have USB connections for iPods / flash drives etc which bridges the gap.
It's getting to the point that even legally accessed music has become both highly convenient in delivery and almost free (I.e. spotify, pandora, etc).
So IMHO, hardware-wise if I was a manufacturer I'd be focusing on speakers, DACs, music servers, or best yet, attractive convenient and good sounding devices that integrate as much as possible all three of those. As much as I'm a hopeless gear hoarder, my experience is that what future audiophiles are willing to splash out extra cash for are things like headphones and Sonos type systems.
