I'm not sure I agree with this. According to this article:

"Microsoft makes more than 75% of its profits from Windows and Office. Less than 25% comes from its vaunted servers and tools. And Microsoft makes nothing from its xBox/Kinect entertainment division, while losing vast sums in its on-line division (negative $350M-$750M/quarter)."
I realize they're trying to position the XBOX One as your home entertainment hub - but the bigger question is whether there's a future for home gaming consoles at all, or whether that functionality will just be folded into your TV, cast from your mobile devices, or handled by some other connected multi-purpose device.
