The screen resolution for Xbox 360 games will be in high definition, so the pre-rendered movies are going to be pretty large," said Itagaki. "If we encoded the Dead or Alive 4 trailer from E3 in high definition in a quality acceptable to us, it will easily be about 2GB." This would leave around 7BG for game data, but for games relying on pre-rendered scenes to tell and develop the story, multiple DVDs may be required. Itagaki added how shocked he and his team were when they were told the Xbox 360 would use DVDs.
