Microsoft working on next Xbox

"Of course we're thinking about [the next Xbox]. We're constantly thinking about the next thing, we have to. It's my point about complacency - you can't sit back on your laurels in this business - the consumer won't let you, the developers certainly won't let us. So that's happening right now," Lewis reaffirms. "We keep our development cycles very fast and high, that is the nature of the company and how we operate in terms of research and development, and that's no different than any other part of Microsoft."
