I think it's also interesting to note that the 2 millionth PS2 has recently been sold for the Benelux in Amsterdam:

So I think the PS2 (and PS3) figures for "Other Europe" is off quite a bit, as VGChartz states about 3 million PS2 sales in total.
If not PS2 sales in the Benelux is twice that of Switzerland, Austria, Poland, Portugal, Ireland, Czeck Republic, Hungary, Croatia, Slovenia, Greece, Ukraine, etc, etc, all combined!
