At the keynote off the developer-focused Gamefest 2007 in Seattle, Microsoft's Game Developer Group general manager Chris Satchell has focused on the three cores of Microsoft's gaming business: MSN, Xbox 360 and Games For Windows. Xbox Live is a huge part of converging all three, allowing him to reveal some notable XBL statistics in his opening presentation.

Satchell says there are currently more than 7.1 million Xbox Live users and, more surprisingly, those users have conducted more than 25 million downloads on Xbox 360.

Additionally, they're finding the attach rate for Xbox Live Arcade titles is more than 6-7 per user - and that number has doubled in the last four months. By the end of the year, Microsoft expects there to be over a hundred titles on the service; right now there are 77.
