There is a rumor going around that by the time that metal gear solid 5 comes out (propably another 4 to 5 years) that kojima is planning to release mgs4 for the 360. I am not saying that i believe this, but the source that i heard this from has so many details to support this fact. Again i'm not saying that it is true but all of you metal gear fan who are planning to get a 360 might want to keep an eye out for that release.
