Following last night's shock news that Final Fantasy XIII will release on Xbox 360, VG247 has been told be a very senior UK industry source that an 360 version of Metal Gear Solid 4 is "inevitable".
"There's only MGS left now: for a few months at least," said the mole. "It's inevitable. Konami knows how many million they'd sell in the US alone. If FFXIII can make it to 360 when Sony owns nine percent of Square, Metal Gear's a slam dunk."
