From the article:
''The Gamerscore Blog would like to congratulate Rockstar on the launch of Grand Theft Auto IV. GTA sold over 6 million units, and broke the entertainment record with over $500 million in sales.
I got some data from the US team, and I'm here to share that news with you:
* Actual MS sales data from last week shows Xbox 360 console sales at retail went up 54% week-over-week as a result of GTA's success
* According to retailers more than 60% of all GTA games sold in the first week were the Xbox 360 version
* Retailers are telling us that the game is attaching strongly to new console sales, with roughly 40% of new consoles selling with a copy of Grand Theft Auto IV''
