World of Risen has the announcement of Risen 2, the sequel to the role-playing game created by Piranha Bytes after they left the Gothic series (thanks inCrysis). Apparently the Gamescom announcement said the game is coming for Windows and unspecified consoles, but here is the entirety of the news post:

During the press conference at the gamescom 2010 in Cologne, Germany, Deep Silver confirmed officially that Piranha Bytes and Deep Silver are currently working on "Risen 2". Daniel Oberlerchner, brand manager of Deep Silver, also reported this in our forum.

While this is no big surprise for most people, it should discard any speculations and rumours about other projects (i.e. Gothic 5) currently developed by Piranha Bytes. The next game will definitely be a successor to Risen.
