What StubHub is doing by prematurely posting tickets at $1,000 is creating a speculated market. In other words, in the event that this revival IS as huge as expected, this $1,000 would be a bluff-come-true (shoot high and see if someone bites). Remember, back in April 2001, companies like StubHub (which is basically a ticket broker outlet) were getting $1,400 per ticket for the brand-new THE PRODUCERS without ANY problem. I remember in literally less than 3 hours, the morning after the show opened to raves and to huge lines outside the St. James Theatre, prices thru ticket brokers started at $300 per ticket around 11am. By 2pm, those same seat locations rose to $1,400 per ticket AND they couldn't keep them in stock. THIS madness is what gave birth to the Premium Seating option that now exists. Before THE PRODUCERS, this never existed.
Due to the current economic state of this country (and the world, for that matter), that current $1,000 asking price will plummet to more than half that once the show arrives on Broadway. Ticket brokers are no longer charging astronomical prices they once did since many can't nor will pay those crazy prices anymore. Since they can't sell them, this explains how and why you can get sensational last-minute tickets are low prices thru them. They feel its better to get something for them than lose their entire investment -- thus they are selling tickets they paid $350 for at $100.
There you have it, folks.
