Nintendo Wii sales drop on dearth of hit video games

Being a video game console maker is a lot like being a movie studio: you're only as good as your last blockbuster. And these days, thanks to a lack of blockbuster game titles, fewer game consoles are moving off store shelves.

The Nintendo Wii, the Sony PlayStation 3 and Microsoft's XBox are getting old. What boosts sales of aging consoles are hit games. Nintendo (NTDOY), Sony (SNE) and Microsoft (MSFT) are hungry, maybe desperate, for hits.
