I voted Maybe because this is really hard to nail down.
Whatever the boost is basically happens during the week of Halo Reach's release, but it may not be just because of that but some more interested in the new 360, those preparing for Kinect that liked the TGS reveals, etc.
But I know that, unless we can read minds, this is the only way to measure boosts. Its imperfect but it is what it is. Still, not sure if it'll be more than 65k based on the only known sales figures we have for the game.
