Microsoft's Phil Spencer will soon lead the Xbox, Xbox Live, and the "creative teams including Xbox Music, Xbox Video, and Microsoft Studios." Spencer himself heads the latest Xbox blog update about his new role.
The growth of the Xbox community, with over 80 million Xbox owners around the world, is built on the foundation of exclusive franchises, new and original IP and the world’s most popular cross-platform games. Games and gamers have always been at the core of Xbox and the core of my work—and gaming will be our core as we take Xbox forward.

This past year has been a growth experience both for me and for the entire Xbox team. We’ve taken feedback, made our products better and renewed our focus on what is most important, our customer. Our mission is to build a world-class team, work hard to meet the high expectations of a passionate fan base, create the best games and entertainment and drive technical innovation. As we continue forward, this renewed focus and mission will be a foundational part of how I lead the Xbox program.

Spencer promises that fans will "hear much more" concerning the Xbox brand as E3 approaches.
