The German and Austrian versions of South Park: The Stick of Truth have been delayed, due to the presence of swastikas in the game.
Such imagery is prohibited in both Germany and Austria, but it appears that the copies shipped to those countries still included the content. The most obvious validation of this was during the release of Black Ops when the swastikas got replaces with eagles.
The game is still set for regular release everywhere else. You can pick yours up tomorrow in the UK and Ireland.
