Joystiq has some rather astounding news from the Tokyo Game Show today. A software update later this year -- we would guess the scheduled fall update -- will add full 1080p capability to your Xbox 360. Still no word of an HDMI cable, though. Right now this is only via component or VGA. Still, Microsoft is promising immediate upscaling of all existing games and DVD movies. Huh, it looks like the 360 is capable of "True" high definition after all. The question is: can it play games in 4D? Stay tuned to X360F and Joystiq for more breaking TGS info.
