I always assumed it would. Back when the successors to Windows were named Longhorn and Blackcomb and they were taking a decade to release, I assumed they had gotten smart and we're going to play with Apple on top of BSD or other Unix. There were always rumors that internally, many MS programs compiled on Unix. In any case, I still think it's a smart move. It doesn't mean IIS or MS SQL Server need to go away or would even lose market share. (But I'm stating that as a "perhaps," not a fact :) ) If not, at least they're pushing many of their core technologies to it (.NET, etc.) so it's still a net positive.
