People don't buy Windows Servers for the kernel specifically, they buy it for the technologies that run on it. Same with Windows desktops. Remember, the kernel portion of Windows (and related OS areas) is a major cost center for them, not a profit center. MS sells applications, development tools, server software, and gui's across servers and desktops, not kernels. :)
I agree that MS wouldn't adopt the Linux kernel (licensing issues), but I do suspect they will adopt BSD and follow in Apple's path, and probably sooner than later. This would NEVER happen with Ballmer, but with Satya Nadella in charge it becomes a real possibility. After having done OEM Windows OS development work I can tell you underpinnings of the OS (ala interactions with several craptons of various hardware) is expensive to develop for and even more expensive to test for. In my case that was with MS already having done the most expensive heavy lifting under what my team was doing. Why not "outsource" the lowest levels which allows Microsoft to then concentrate on the MS technologies that actually make their money - AD, Exchange, SQL, IIS, S!@#epoint, etc?
