The Japanese Ninja Gaiden site is very light, carrying only the bare minimum of what it needs to qualify as a promotional game website. This is the ancient way of the ninja. It has to be silent and quick, ready to dart into the shadows at a moment's notice. Thus, we get nothing but a splash screen and a scrolling display of small screenshots.
Unfortunately, it also bears some news that you may have already figured out: the game won't be coming out in November as planned. The website lists the game's release as "planned for March 2008." Too bad for those of us looking to pick it up in negative one month.
