Very clever click bait headline by Fox Business.
AppleTV, Chromecast, FireTV means no chance of this happening. Xbox is clearly not a distraction since Microsoft's main competitors are going after the living room.
Before and after Xbox, Microsoft made many attempts for the living room and tried webTV, UltimateTV, Media Center, MediaRoom. Xbox is the only success story they've ever had in the living room. When
Microsoft sold off MediaRoom and all of their IPTV technology to Ericsson last year that was their declaration that they were all in with Xbox as their living room play.
Xbox with universal apps, bing, skype, onedrive, Xbox games, movies, TV, music, not to mention Azure usage in games is a platform for Microsoft software and services. Take away Xbox and the draw of the Microsoft ecosystem of services is only further diminished. If Microsoft doesn't mind giving 30% of their software revenue to Apple then I guess Microsoft doesn't need their own platforms and they might as well kill Windows too.
A spinoff of Xbox is an option for a company in dire straits, not for a company making $6B profit every quarter.
