So how much of the tickets wil end up on stubhub?
I'm sure there will be plenty, but my guess is that it will be less than for most shows like this. There are costs associated with selling hard tickets (fed-ex, etc..), and the limit of four per person means that the return to sitting in line can't be that great.
They could have done the ID check thing and made it harder for resale, but of course that means the lines to get in would be brutal.
I'm ok with this as a distribution system, though I think it would have been better if they limited it to two tickets per person in line.
