Can you explain Nintendo's announcement/reveal strategy?

And Nintendo as a company was worth 1 billion more before the announcement.What does this mean?Nothing.Its just the market being the market.

I heard Apple's stock go down at times when they announce new products. Is that right?

If you say so, must be!I mean, I heard that the PS4 is having so much success, that the investors are backing away and instead going all in on the XOne.Man, what a twist!
