A recent article on Yahoo News comments on how the Wii may be losing its grip on the console war in Japan. Nintendo president, Satoru Iwata, said that the Wii is in a very "unhealthy condition," right now, and that the PS3 is actually outselling the Wii for the first time ever in 16 months. That's a big deal!
The article also goes on to say that the one thing Nintendo DOESN'T want to do is have a price cut, as a price cut in a economicly vulnerable time like today wouldn't really bare any fruits in the long run, so it's not even worth doing. They might be right on that one.
