I did my part for that *wwwoho* ;)
No seriously it isn't that surprising. Microsoft is such a bad brand name in Germany. The price of the WII is in the range, a lot of people consider to get just because they want in or as birthday present. The X-Box / PS3 is in a price range for X-Mas.
I wouldn't be surprised if the PS3 can sell out the 360 2:1 at X-Mas in Germany, and is not that much sold at bye the WII like the rest of the year.
