Like NJ5 said, the holiday drop isn't over in Japan yet. But next week it will, and Jap PS3 sales will drop another 10K, which will give us a worlwide total with the PS3 - X360 being neck to neck.
So what does that tell us about the X360? Well it says that $350 is the pricepoint where it has to rely on good games to be on par with the Blu-ray equipped PS3 at $400.
But what's the next big thing that'll happen? MGS4 coming out? No, a X360 price drop, and there we have the X360 pulling ahead in ww sales once again.
