According to the app (Shameless plug - http://amextickets.azurewebsites.net/) it looks like the game really has sold out now...unless they find a few more seats from somewhere I expect the ticket exchange to open.
ABS.
I suspect more will be released in the upcoming days and then these will be available.
Unfortunatly my app can only count the ones from the website to stop people from having to count seats.
As for the vs (seagulls logo) I spotted that...when I wrote the app I grab all the details from here...
