Does anyone know how many tickets are up for grabs when they go on sale for the B-Day bash, I know they sell out extremely fast and was just wondering how.many are available for each show. Thanks

I know its extremely early, but i was wondering how people felt about the ticketing system this year and if it will be the same for next. If people are on the sight when tickets go on sale how likely are you to get them, in otherwords how quickly did the shows sell out.
