I'm all for microsoft buying square-enix for one, and one reason only.
Square-Enix + Microsoft = Squaresoft!
Aside from that, I highly doubt microsoft would be interested in buying square-enix, Its more likely they'll chip into Vivendi's or EA's assets before going after japanese gaming companies.
I can see them buying Bioware, or any number of north american companies before they buy square-enix.
