No, they won't. There's 3 different versions of Windows 10 now: Home, S, and Pro (and Enterprise for big corps). People who don't like the limitations of S are free to buy one of the other two versions, and they'll probably even an easy way to "upgrade" to Pro for $$$. Over in Europe, if that's not good enough, they'll just eliminate S and stick with the other two versions, and let only Americans get suckered by the S version.
