The holidays certainly contributed, but looking at the numbers, I'd have to think that at least some of the increase was Halo 2 related. I certainly understand that it is pure conjecture. Throw a number out there... 150K units? 200K units? Unfortunately, as stated, the holidays plus other games, plus the age of the data skew things a bit.
At Kber -- I'm speaking in terms of the period around Halo 2. Not just first week or so.
