Mario Pressured to Jump to IPhone as Nintendo Wii, 3DS Slump

In “Super Mario 3DLand,” Nintendo Co. will make its iconic Italian plumber battle turtle-like Koopa Troopas on its 3-D player. The company instead should develop titles for Apple Inc.’s iPhone, investors say.

The rift highlights the dilemma President Satoru Iwata faces as consumers shun Nintendo devices to play games on iPhones, iPads and Facebook Inc.’s website. The flop of the 3DS debut prompted the company to cut prices 40 percent in Japan and 32 percent in the U.S., the first time the games developer has resorted to such a move within six months of a product’s debut.
