My view is likely flawed, but I'll type it anyways.
Let me start by saying that yes, LPs are very, very popular with the younger crowd, myself included. But I have noticed some hostility between individuals on other forums regarding "vinyls." Hostility such as harsh criticism of newbies and their newbie setups (even though those delivering the criticism don't have much more impressive gear), and criticism of other's taste in "vinyls."
It just seems like some younger people are beginning to realize that record listening/ collecting isn't making them as much of an individual as they once thought. Perhaps they will take their interests elsewhere? I don't know.
I've noticed the same sort of trend with craft beer as of late.
But to OP's question, 2013 will tell us.
mmm, craft beer:beer:
