Probably not too much. Just what they do as a matter of course: Provide a reasonably good UX, reasonably good compatibility and reasonably good security. If they do that, inertia will supply middling to good sales. But hey - I can't know the future. I just expect that Microsoft will keep doing what they've been doing. It has worked OK so far, with a few notable exceptions.
