A few people have emailed me regarding something Steve Ballmer said earlier today about a new Xbox coming in 2010. As the Xbox team stated at E3 two weeks ago, we are not even halfway through the current console generation lifecycle and believe Xbox 360 will be the entertainment center in the home for long into the next decade. Project Natal will be an important part of this platform, but we have not confirmed a launch date at this time.
Edit: Steve clarified his comment to IGN. Thanks Steve.
