I would argue that Nintendo's problem isn't that its market has moved to mobile, the problem they face is that the market they want and need (console gamers) has moved on without them. I can't think of a single third-party developed game on a Nintendo console that excited me since Capcom put a bunch of Resident Evil games out on the GameCube. Nintendo itself owns a nice catalog of IP but you can only make so many Mario and Zelda games before the golden goose stops laying eggs. They need other developers making new titles, and good ones. They need a 'killer app.' People stopped buying Nintendo consoles for Mario after the GameCube and quit buying them for Zelda after the Wii. Nobody has bought an N console for a third-party game since the '64. Frankly, the last one I owned was a Super and now I play the remakes of the great games of that console on Sony and Microsoft systems, or emulate the originals on my PC or mobile. Nintendo is not Sony or Microsoft; their problems will not go away eventually by propping up their game division losses with profits in other sectors. They need good games or they are done in a few quarters of bad losses.
