Diomedes is just an inherant PS3 fanboy, and hates the idea of even more top-tier IPs going to X360.
IMO, we'll see MGS4 on X360. Now, the question is if it'd be day-and-date or not.
Also, I think FFXIII on X360 is a little bit too far-fetched. However, I do think that with UE3 being a new staple in the SquareEnix family of development tools, the X360 has a huge advantage over the PS3 right now due to it. Because of this, I believe MS will try to strike a few deals with SquareEnix on making a few Final Fantasy: Crystal Chroincles-esque games for the X360 (ie, a FF game, but not named), and maybe try to grab lots of more obscure titles to the X360 (I'd love a new Seiken Densetsu on X360).
Back from the dead, I'm afraid.
