You're right, the only reason there is now a "20 year waiting list" is because the only seats that are not subject to seat licenses and can become available to people on the waiting list are in the Upper Deck End Zone. Anybody who is seriously interested in becoming a season ticket holder purchases a seat license. So the only reason to remain on the waiting list is to be able to pretend like you're a great fan and only the tremendous popularity of the Steelers prevents you from becoming a season ticket holder.
