It's Windows, there isn't going to be a change in userbase no matter what MS does.
Windows users will not switch to Linux (but it's the year of Linux on the desktop!) because of the usual issues, but serious (non-VS-using) developers will never use Windows either. As for OSX, Apple hipsters aren't going to spontaneously start using Windows, and Windows users aren't going to start spending 2x as much on their computers any time soon.
