I find out yesterday that Eidos and Crystal Dynamics are in the process of making another game. It's called Defiance, and you can find the site
here.
There's at least four games out now for a director to work with, but I assume there could be a total of three with this new game coming out. The first could be the rise of Kain, the second the downfall of Raziel and his rebirth as a Reaver, and the third this new game.
Seeing the transition from the Material Plane to the Spectral Plane would be great as well.
