The folks at PC Gamer have posted a video of the Modern Warfare 2
credits which shows who has left the company and who is left. The brutal part of the video is that all of the design leads of the game have left the company with large chunks of the rest of the company.
I'm guessing that Activision is learning the lesson that a lot of software houses learn the hard way. The most important part of your company walks in and out of the doors of your company every day and you need to be sure to keep them happy if you want them working for you. Sure there's an economic recession out there but when you have really talented folks you have to keep them happy and fed or they are going to move on to greener pastures.
