Europe is different, and can meana different area depending on which company is reporting it and how they are currently choosing to view the numbers, When Microsoft reports figures for "Europe" they mean UK, France, Germany, Spain and Italy.
When Nintendo does it they add in Benelux.
I have yet to work out what Sony implies, but they buiilt up a much bigger presence than the other two in Eastern Europe the past two generations, so they could mean a much bigger region when they say Europe.... Someone will have to send me a few references to Sony actually stating "Europe" figures somewhere because most of the time it is specific countries they refer to.

If you add up those 5 countries on VGC you get 7.2 million for the X360 as DirtyP has already said.
In Nintendo's idea of Europe the X360 is around 7.8 million (Benelux makes up about 1/2 to 2/3 of "other Europe" section)... but somehow I doubt it.
