In France we have a 2:1 ratio for the ps3. And that's seems true when we look at the charts.
So with near 500k of cod6 sold, and a 60% share for ps3, 30% for 360 and 10% for the rest,
that means 300k for ps3, 150k for 360.
UK+Fr means 1.150k for 360, and 1.000k for ps3.
Including sony land in UE, seems the ps3 is over the 360 in UE.
