IGN is pretty balanced, it already did preview of many games you said. I think this you talk is a fluke of the moment.
But multiplat normally have 360 logo attached first in every site, because of the bigger attach rate 360 has, especially in America. And since most readers that advertisers are interest in reaching are americans, is economically more important to draw more US citizens to the advertises inside the site.
PS:Demon's souls (asian) is my goty.
