Whitten had been with Microsoft since 2000 and helped launch the original Xbox, Xbox 360 and Xbox One. In the announcement post on Xbox Wire, Whitten said the following:
"I have had the extreme pleasure over the last 14 years to work on the greatest product with the greatest team and for the greatest community. Xbox is so special because of the amazing team I've had the opportunity to work with and because our fans are the most incredible fans on the planet. It has been the highlight of my career to work on a product so loved. It's incredibly tough to leave but I am confident the best days are ahead for Xbox fans, in the capable hands of a very talented team."
The remaining Xbox team leadership will remain intact, the post said, and Whitten's team will now report to Software EVP Terry Myerson.
