This is blatently going to be a RPG or a turn based/strategy game. Theres no way they can do an actual Metal Gear Solid game, of the quality of MGS4, on the 360.
Call me a fanboy, but you need some hokus pokus' to do that.
You have such a one track mind.
Edit - The timer is still going. i wouldn;t be surprised if there was a MGS5 for the PS3 and 360 gamers get this.
