Kojima's new MGS4 trailer crashed during Konami's press conference yesterday.
Kojima stood up and spoke a little bit about his franchise at the Games Convention, and then was ready to debut the new Metal Gear Solid 4: Guns of the Patriots trailer.
The lights dimmed, and everyone saw Snake sneak behind Ocelot with soldiers everywhere.
Then, there was a roar of sound, like a loop of gunshot noises and action. Everyone knew something was wrong. The soldiers fell, and constantly repeated the same animation.
Kojima didn't care, and put the blame on a technical error. He then went on with his presentation and stated that a special guest from Japan would be present for tomorrow's Metal Gear Solid 4 conference, where hopefully a working trailer will be shown.
