At the prices they are trying to charge I would be very surprised to see this thing sold out quickly. They may eventually fill the thing but it will be due to reduced pricing or special deals just to fill the seats for TV.
At the end of the day an outdoor hockey game is just a novelty, most of the site lines are going to be absolute garbage. Sure there will be a market of diehards that can't miss a special event but beyond that dropping 250-400 a seat is going to be a tough sale. Technically they have 110 dollar tickets in the nosebleeds but that sounds even worse to me.
I was in the first pre-sale group the other day and a ton of tickets were already marked unavailable. I doubt that means they are already sold, they probably only blocked off certain sections for the pre-sale.
