As Buffed.de reports on their website, Drakensang developer Radon Labs filed for insolvency. It seems an investor pulled out of the officially still unannounced Drakensang 3 project, which made the walk to the Berlin district court necessary.
Radon Labs was / is also working on Phileasson's Secret, the add-on to Drakensang: The River of Time. According to the same source Radon Labs has already started take-over talks with interested parties.
