This is a Japan-only thing for now, but Nintendo's just announced two brand spankin' new colors for the Wii. The two colors are Jet Black and Ocean Blue. (seen below)

Although we'd really like both of the colors to hit the US, Nintendo's held off Japan colors before. DS Lite color options showed up in Japan first as well. Pricing for the Wii has been left unchanged at 25,000 yen and both will include Wii Remotes and Nunchuks in matching colors (Also sold seperately at regular prices).
Now, the question is how long before this hits the US?

Holy crap, it looks like Nintendo is striking back at MS's price drops with a showstopper all on its own.
