Oh and I should also add the Lifetime sales here in America according to the NPD as of the end of May.
X360 - 10,270,000
Wii - 10,180,000
PS3 - 4,450,000
According to this, the 360 only had a 90,000 unit advantage over the Wii by the end of May. This means that the Wii has overtaken the 360 by now since it's already mid June here in North America, and next months NPD will provide the factual proof. This means the Wii is now the offical market leader in every single major territory in the world.
