Remains to be seen desu, the original Punk debut sold out basically instantly but it was heavily scalped and by the time of the show they were selling tickets for just a few dollars, so scalpers heavily overestimated demand and lost a lot of money. Pic related is what it looked like once resale tickets were posted on Ticketmaster.
When the resale tickets are posted, IF they are significantly lower than for the original show then I'd say that 6k for the first day of sales is probably an okay number.
