"Overview - The ‘USA Pre-order’ article has been changed slightly. There will be a greater focus on games that are in their final week before launch and how it is compared to previous game in the series. The ‘USA Preview’ article will now be incorporated to give an early look at what is expected for games that are already out. There will only be one article from now on based on the USA pre-order and USA preview data. Expect to see similar articles for other regions in the future.
There are three games in the top 30 to be in its final week before launch, Tales of Graces f (PS3), Mario Party 9 (Wii) and Silent Hill: Downpour for the PlayStation 3 and Xbox 360.
The top four games have 200,000 or more pre-orders, down from five last week, and the top 10 has 100,000 or more pre-orders, down from 11 last week. One game adds 20,000 or more, down from three last week and three add 10,000 or more, down from six last week."
