The reason why Nintendo's stock only fell 10% in the wake of the Wii U's unveiling was because the US capitalist market isn't stable yet. I read somewhere that anime series are funded by American distributors; whereas, Japan cannot keep their anime studios from losing profit. Rumor is the average age of a gamer is 35 and they increasingly deal with marriage, raising children. There is more cinematic movie games that fail to stop the decline of videogames.
Maybe Wii U and 3DS can save the game industry with their Legend of Zelda, mario kart, super mario WIIU, Super Mario 3DS, Metroid Prime, Super Smash Bros., Pikman, Luigi's Mansion 2, and third party titles Metal Gear Solid and Final Fantasy.
