Last week there was a huge adjustment that pushed the PS3 (+20k) above the 360 (-50k). This week a very minor adjustment is all it would take, 1.7k. I won't concede the win to the 360 till I see what the numbers look like after the adjustments come in.
The Wii dominated them both though.
My prediction (Jan 15th, 2008), total sales by end of 2008:
Wii - 35 million
X360 - 25 million
PS3 - 21 million
