According to Ripten, who say their source spotted "the game on a certain pre-release network", Metal Gear Solid could in fact be on the way to an XBLA release. If their source is to be believed, the game appearing on PartnerNet is almost a guarantee that it will see release at some point (though sometimes many months later, as was the case with Ikaruga.) While the Xbox isn't traditionally the home of the series, a port of the second game did find its way there, so perhaps a port of the first isn't so out of the question after all.
