I dunno. It gets a ton of hype from MCDM, one of the largest sources of fun promotion of RPG things out there besides WotC themselves or GenCon. And there were 23 tickets sold at GenCon. Not tables, tickets, individual seats.
Maybe that has more to do with availability but I'd think a newer generation would embrace PDF and POD more and the original character builder is still out there, no idea if it's still getting maintained but I'd bet it is and works on current hardware/OS.
Outside of those pushing into the OSR, I think this underestimates the counter-push when it comes to playing older editions of anything, available PDFs or not. There's always a lot of incentives if getting into a game to play the most recent edition of pretty much anything.
