VGChartz adjusted last weeks numbers today which changed the PS3 from being 2k below the 360 to being 9k above.

I don't really expect that to hold for a 3rd week, since PS3 is dropping back down in Japan this week. Though if a lot of people were out to buy Blu-Ray players in US on Black Friday, it is possible.
My prediction (Jan 15th, 2008), total sales by end of 2008:
Wii - 35 million
X360 - 25 million
PS3 - 21 million
