Impromptu Nintendo event has investors (and gamers) giddy

Nintendo announced an unexpected Japanese press event yesterday for Sept 13, two day before the Tokyo Game Show.

Following the news, the company’s stock priced jump, as investors expect Nintendo to unveil a revamped 3DS that day, reportedly one with a head-scratching second analog stick and a de-emphasis on 3D. (!)

Not sure if that would excite the masses. But who knows, Nintendo has surprised us before.

Either way, what would Nintendo have to show on that day to get you to buy a 3DS?
