Sure it more than likely Microsoft would not spin off the Xbox division, but those acting like this is completely out of the realm of possibility are being pretty naive. Considering there has been recent rumors of talks with Amazon (whether they are true or not is impossible to tell).
Couple with the fact that the division isn't exactly racking in a ton of cash, and is such a small piece of Microsoft's overall pie if they got the right deal they would easily dump it especially with its early struggles out the gate and the general consensus that console gaming market is likely to decrease due to mobile and F2P gaming models. I still bet they keep it, or at least ride a few more years into this generation and see how it goes. But I would not be the least bit surprised if they found a more eager company to spin it off to because honestly Xbox isn't that big of a deal to Microsoft. They wouldn't even lose sleep over it.
"While the Xbox One and Xbox 360 sold 3.9 million and 3.5 million units respectively, gross margins for the Devices & Consumer Hardware division were down 46% to $0.4 billion."
