The US dominated sales patterns through December and 360 total dominance [of the current gen consoles] there will ensure the gap widens from here through to probably January week 1 or 2.
Then it will be interesting to see the Post Christmas Wii U effect on PS360 sales. I think Wii U will tend to eat into PS3 sales more than 360 sales mostly due to Japan. I think prospective PS3 buyers in the USA will go for Wii U in larger proportion than prospective 360 buyers. Outside USA and Japan it might be an even move to Wii U away from PS360. But I don't know whether, on a global basis, Wii U will have a 5, 10 15 or 30% depressive effect on PS360 sales. So PS3 relative to 360 in 2013 is very up in the air.
