John Schappert, the firm's corporate vice-president of Live, Software and Services, said that he would “love to see the game come to 360", and boasted of Xbox’s “horsepower”.
His comments came after Konami’s Yoshitaka Arai allegedly told a Japanese newspaper: “The worldwide demand for an Xbox 360 version of MGS4 is quite high, and it is something we are currently looking in to.”
Sony US boss Jack Tretton previously told MCV that MGS4 on Xbox 360 was an "impossibility".
Schappert told MCV:
“I’m certainly in the fan club that would love to see Kojima-san’s masterpiece come our way. It would be wonderful to play Metal Gear Solid on the Xbox. It could become another of the many franchises that started their life on another console that are now coming our way.
“I can’t speak on behalf of Konami, but I can shed more light on the fact that we definitely have the power to run MGS4.
"There are a lot of recent examples that are in true high-def on our platform and aren’t on PS3. We’ve got an amazing amount of horsepower and graphics power.”
