How much of a boost will 360 get from Halo 4 in its first week of sales?

Is really difficult to say because the time of the year will already create some boost compared to last week..

I would go with 30K boost for the time of the year + 75k for Halo 4.

So a little + 105k boost... but because I low bailed my last estimates I raise it to 150k boost.
