It wouldn't bother me that much if Microsoft bought Capcom. It would certainly not drastically change the gaming world--the Xbox is just not popular in Japan, and Microsoft owning Capcom would not change that overnight. I've been itching for a solid Xbox Live version of Marvel vs. Capcom 2 or Street Fighter Alpha 3 or Capcom vs. SNK 2, and maybe Capcom would actually make such a thing if Microsoft bought them. Who knows.

MGS4 on the 360 is a bigger issue, I think, and personally I'd like to see it happen just so I can play it. With so many different people offering differing opinions as to the power of the two consoles, I'm not really sure if the 360 version could keep up with the PS3's or not. I sure hope it could.
