To be honest XBOX division does not mean much to Microsoft financially. They secure most of their revenue through Productivity/Business Tools (Office), Cloud Computing (Windows Azure) and Windows nowadays. Their gaming revenue (XBOX console, games, subscriptions, etc) is ~$1.5 billion, 80% less than that of their business division, and it has stopped growing for a while (-5% last quarter I remember).
It is actually pretty sad for Microsoft. With Windows getting irrelevant (as people spend more and more time on mobile platforms), Bing never becoming popular and XBOX slowly withering, the company is indeed fading out for general consumers. Their business division is doing pretty well, though.
