March 3 was the last day for Amy Hennig. She was the writer of the Uncharted games on the PlayStation and she was working on the PlayStation 4 Uncharted game when she left.
Sony has confirmed to IGN of her departure, but why she left is still a mystery. Sources told IGN she was forced out, but no reason why seeing as she did a pretty good job with the first two. The third, for me, was just OK.
Now, it looks like the directors behind The Last of Us, Neil Druckman and Bruce Straley, will be taking over. They've worked on the first two Uncharted games and are the ones rumored to have forced Amy out.
