According to his LinkedIn profile, Mask of the Betrayer lead designer and Star Wars: KotOR II senior designer Kevin Saunders has left or been let go from Obsidian Entertainment. He was most recently working on the Aliens RPG, so one would think that his departure might be connected to rumors of its cancellation back in February.
It looks like he's already landed a job at Alelo, but hopefully we'll see him return to RPG development sometime soon.
