According to VGChartz the gap between the 360 and PS3 is now 6.75 million.
However we know the PS3 is slightly undertracked for the UK and Australia based on MCV/Chart Track/GfK/Sony [Bravia figures], probably by about 50K in total.
And according to VGChartz the 360 outsold the PS3 in January for North America by about 62K, while the NPD reported the PS3 outselling the 360 by about 60K for just the US, so that's another 122K of difference.
So the difference is probably closer to 6.56 million assuming no great difference for other regions. However assuming christmas sales (UK 20-22% of the European PS3 market) and PS2 sales ratios for SCEE are representative there may be another great gap, this may put the actual difference close to 6 million.
6 million considering Blu-Ray victory, fewer XBox users upgrading to 360, continued 360 reliability issues, a much better high profile PS3 game line-up, PS3 Home, PS3 PlayTV introduction, etc IMO 6 million seems like a possible figure to master by christmas 2008. (both consoles may drop in price though)
