Alright, so Konami's secret, poetic announcement turned out not to be Metal Gear Solid 4 for the Xbox 360. It turned out to be Silent Hill 5 (which is actually bigger news for some people). Still, a good rumor never dies (and a great rumor comes true). While the MGS4 360 rumor has yet to come true, a reliable tipster tells us that Official Xbox Magazine has taken it upon themselves to toss another log on the fire. In the most recent Rumor Mole section, OXM declares that a "bankable source" told them that Metal Gear Solid 4 is definitely coming to Xbox 360. The game is reportedly being ported by a separate team -- which isn't headed by Hideo Kojima -- and should ship "a few months" after the PS3 version.
Considering the ever-mounting rumors and Konami's own comments on the matter, it's starting to look like the only thing missing is an official announcement.
