when will Microsoft release its next 360 bundle pack

i haven't seen them for a while in stores. how often do they sell the 360 that comes packed in with a game? also what game do you think will be the next game that will come bundled together?

The old Christmas Bundle. Xbox 360 S 250GB with 2 controllers and 2 pack in games. Or they may do a kinect Bundle with 3 Throw-away Kinect games.

Won't be one til holidays and I'm willing to bet

Lego Harry Potter Years 1-4 and Split/Second (or Blur)
