Microsoft Boasts Healthy Attachment Rates For XboxFollowing the recent release of titles such as NCAA Football 2007, Prey, Chromehounds and Lord of the Rings: Battle for Middle-Earth II, all of which have secured a place in the 360 top ten, the software attachment rate rose to 4.6 games per console this month. The Xbox 360 also has the highest accessory attachment rate among consumers, with 2.9 units sold per console. Microsoft also announced that more than 80 per cent of Live users have downloaded content from Xbox Live Marketplace - bringing the total number of downloads to more than 46 million. Almost 70 per cent of Live users have downloaded music videos, movie and game trailers, and 65 per cent have downloaded at least one game from Xbox Live Arcade. The number of Xbox Live Arcade downloads since launch now stands at more than 8 million, and the most popular titles are Geometry Wars, Uno, Bankshot Billiards 2, Marble Blast Ultra and Street Fighter II Hyper Fighting. Microsoft did not reveal how many Xbox 360 consoles have been sold, but reaffirmed that it plans to ship 10 million units by the end of the year, with a library of more than 160 software titles. The Redmond giant went on to predict that between 13 and 15 million consoles will be shipped to retail by the end of the fiscal 2007 period next June.
