Don Coyner, lead designer and marketing man for the original Xbox and the Xbox 360, will not be in charge of the new Xbox design team, Cnet reports. Coyner will be replaced with Emma Williams, who helped launch the recent Xbox Live interface revamp, one of Cnet's sources says.

Coyner joined Microsoft from Nintendo in 1995, and became marketing director for the original Xbox in 1999. Coyner designed the user experience and branding for the Xbox 360, and his most recent title at Microsoft is General Manager of Design. Williams joined Microsoft in 2003 and is currently General Manager of Xbox Experiences, leading last week's Xbox Live interface update that introduced more social, content-specific hubs to the 360.

With the next Xbox rumored for release in 2013, the Live update could be a massive trial period for features to include in the new model, or it could be a secret government study monitoring the effects of cloud storage on adolescent violence. Could be.
