lal, MGS4 will not be coming out for XBOX360 as you may have already known. Reason being is because of the Blueray disk has been filled (Yeah 50gb). This is most probably down to the cutscenes, its definetly not effected the ingame textures but the game creaters said quality could have been better if they didnt have to compress everything.
Maybe because they put MGS4: Online on there too but theres no way that would have effected it. Roumer has it that theres a 90minute cut scene FMV! Shame they didnt just use another disk for the extra content baring the prices. Its a bit too late for Hitatchi though as there working on stabalising 100gb blueray disks (Link here).
This is what it would look like IF it was out for XBOX360
