This is not to say Staten is working on Halo - that's the role of 343 Industries which is a subset of Microsoft.
Indeed, it's been er.. stated:
"Joseph is not working directly on the next Halo title. As a senior creative director, he will help create the world's best entertainment on Xbox, as well as help shape our franchise strategy for some Microsoft Studios titles. He'll also be one of our leading ambassadors to the game development community, building on his many years of experience and relationships with developers and fans. We're excited to share more about Joseph's role in the future."
Staten has spent 4 years writing the new Bungie game Destiny, so his legacy at Bungie is not yet even truly begun!
