i just checked an austria ticket site http://194.158.136.97/cluboe3/suche_...LAND=99&LOOK=J (direct link) and saw that they sell tickets for another sector cause it would be sold out i assume :P ; yet there are only seats to gather- one is category 4 at a price of 50€ and cat. 2 for 55€ unfortunately they don't tell you the sector belonging to the category so i can't really tell you where it is but i think the more expensive the better sight
my friends and me all have standing GA tickets- which means with luck you get directly in front of the stage

btw: the site is in german and AUSVERKAUFT means "sold out"
