Microsoft claim gold across the pond
Having proclaimed sales victory over the PS3 in Europe, with 55% of GTA IV copies sold on Xbox 360, Microsoft also state that they have taken North American as well - claiming that 60% of games sold were for the 360.
The official Gamerscoreblog cite their own figures as confirming the victory. "According to retailers more than 60% of all GTA games sold in the first week were the Xbox 360 version," states a new post on that website.
The team also reveal that 360 sales were up 54% with the release of GTA IV, 40% of consoles accompanied by a copy of Rockstar's new opus.
GTA IV is also the most popular game on Xbox Live presently, topping previous leader Call of Duty 4 by some margin. More shortly.

not impressive being that there are way more 360 out there
my thoughts exactly, since there are so many more 360's out there, this percentage is flawed...
it actually shows the PS3 fanbase reallt turned out to get GTAiv..
