By now, you must have heard the rumor of Bungie leaving Microsoft that started at 8Bit Joystick.com. Since then, Game Informer has reported that their own source stated "for an unstated, but significant amount of money, Bungie shareholders bought the studio name back from Microsoft."
Now, TeamXbox has also reported that they have sources, and that there is indeed something "more complex" going on between Microsoft and Bungie. Here's what TeamXbox said:

There will be an official announcement this week, definitely before October 12th..."
