In an interview with 1up.com, Hideo Kojima (the creator of the popular Metal Gear Solid series) mentioned that it was technically possible for Metal Gear Solid 4 to run on Xbox 360 hardware. He also stated that they chose the Playstation 3 hardware to run the MGS4 trailer was merely because it was 'newer' and they wanted to try it out first. Kojima also said that there weren't any real differences between PS3, PC and Xbox 360.
