From what I understand, they can readily afford to make these bets though. If Switch turns out not to be another Wii, but rather a WiiU, that's no sweat to them and they can easily figure something else out.
Them and Apple... two companies so swaddled in money that they can't even hear their consumers anymore.
Shareholders aren't impressed by "our quarterly losses only burned through a tiny portion of our stockpile", though. The pressure on Nintendo to deliver with the Switch is quite high.
