My take:
At a point in time, Nintendo was top 10 in terms of marketcap in Japan. Now it's a shadow of its former self.
Nintendo has a lot of structural problems that a simple 80$ reduction won't fix and a lot of smart money are taking notice. The company is structurally broken and its business model one generation away from being out of date (if it's not already).
Its portable division, after twenty years of being the market leader, now will not be able to keep pace with smartphone that will out power the 3DS, most likely by next year.
the Wii U is not even out yet and Nintndo is trading below $20/20k Yen, when the Wii U comes out and underperforms, Nintendo will have another leg down.
