"Our vision is that every person can be a creator. That every Xbox One can be used for development," Xbox corporate VP Marc Whitten told Engadget. "That every game and experience can take advantage of all of the features of Xbox One and Xbox LIVE. This means self-publishing. This means Kinect, the cloud, achievements. This means great discoverability on Xbox LIVE. We'll have more details on the program and the timeline at Gamescom in August."
Before this revision, Microsoft's Xbox One policies required developers to be paired with third-party publishers or publishing deals from Microsoft itself, making no exceptions for self-publishing.
