I would guess that they would be exactly the same as this year. I mean they sold out in 90 minutes and plently of people bought scalped tickets for $450 plus. I don't think they would have any problem selling tickets at $350 again.
You guys are insane if you think tickets will be around $350 again. Presale was $300 last year. If presale is over $250 I'll be pissed. Coachella is $350 for the same amount of days. As much as I love Sasquatch, it is not Coachella. Not even close.
They would need to put together two amazing lineups to think that they could get away with charging Coachella prices.
