Divinity: Original Sin announced adding multiplayer

Lartian Studios are set to release a new Divinity RPG next year called Divinity: Original Sin. The new title will bring a whole host of new features to the series including co-op play for up to four players. The game has actually been in development since the end of 2010.
Original Sin will follow the story of two heroes, a condemned warrior and a mystic heroine who are on a mission to stop the Orcs of Tanoroth who are once again on the march.
The game wil be released on the PC and Mac at some point in 2013 and will be shown for the first time at E3. 
As a quick taster, Larian has this rather nice developer walkthrough of the new features you can expect.
