The statement is directed to the X360 I think. He wouldn't point out that (...) in each territory, there are platforms that are more or less popular than in other territories.
This is only true for the 360. The Wii is strong everywhere and the PS3 weak everywhere (granted, a little less weak in Europe but that doesn't make a difference regarding this topic). The 360, however, is strong in America, mediocre in Europe and close to non-existant in Japan.
