Newsweek's LevelUp blog continues to produce some highly interesting material. Today they have up a look at the 'flight' of game studios from Microsoft's corporate umbrella. BioWare's purchase by EA distances it a bit from their cosy relationship with Microsoft, as does Bizarre's purchase by Activision. Bungie's departure from the company itself goes without saying. So what does all this mean? Is this a sign of troubles in Redmond, or just more fallout from the huge undertaking required to get the Xbox 360 to the position it has today?
