MS: Over 39 million Xbox 360s around the world

Xbox has generated more than $20 billion in game revenue.

Microsoft CEO Steve Ballmer announced during his 2010 CES keynote overnight that there are now over 39 million Xbox 360 consoles around the world.

"Today I'm pleased to tell you that there are over 39 million Xbox 360s around the world. And since we launched the first Xbox, more than 500 million games have been sold, accounting for more than $20 billion in total game revenue," said Ballmer. "We've had amazing momentum with Xbox over the past decade. But it's this year with blockbuster games launching virtually every month, and other surprises in store, that makes me more excited about 2010 than about Xbox ever before."

Entertainment and Devices Division President Robbie Bach also took to the stage, where he announced a holiday 2010 release for motion controller Project Natal and declared 2010 the biggest year in Xbox history.

"2010 is going to be the biggest year in Xbox history, with a yearlong string of exclusive blockbuster titles, including our own Halo Reach and Alan Wake, and our ever growing repertoire of social and gaming experiences of Xbox Live, including Game Room, and the release of Project Natal this coming holiday."
