PS3 sales are quite strong. The numbers for the entire month of all hardware (sans the DS) look a bit low, however.
360, in its third Christmas season and with Halo 3 and other exclusives, only managed to outsell the PS3 by 460k with the lowest price point of entry being significantly lower than the PS3, and the PS3's most adopted model being the $499 version. Looking at it in terms of revenue, the PS3 outsold the Wii.
Pretty impressive numbers for the PS3, that's definitely sure. Now, given the sales gap in the US, it's pretty much guaranteed that worldwide the PS3 is outselling the 360. 2008 is where, in North America, PS3 starts outselling the 360 (especially as we get closer to the fall), barring any significant pricedrops by Microsoft.
