It seems like Nordic Games is re-releasing Arcania: Gothic IV on Playstation 4.
The news of the current generation re-release comes via a retail listing on Amazon Germany, which has the game listed as Arcania: The Complete Tale.
The game is also listed for a May 29th release in Germany, and it includes the original game, as well as its expansion Arcania: Fall of Setarrif.
In case you missed it, Nordic Games also have The Legend of Kay Anniversary listed on Amazon Germany for both Wii U and PC.
For now, file both of these as rumors until we get word back from Nordic Games.
