It has been released at the end of June 2012 in Europe, but not in Germany, because the initial publisher (dtp Entertainment AG) went insolvent in April 2012. This Release had been dated to June 29th 2012 in Europe and August 17th 2012 in Germany, and the informations on top of this thread relate to the final release in Germany (despite being a few days between stock (August 17th) and the file release (August 13th)).
