This is one of the dumber things I've read, Wii & DS are Nintendo's most unique handheld and console ever and sold over 250 million units of hardware, nearly 2 billion units of software and make something like $15 billion dollars in profit over 5 years.
These devices didn't hurt their reputation, 3DS & Wii U hurt Nintendo's reputation by having awful strategies that go against what made Wii/DS so successful.
When the herd loses its way, the shepard must kill the bull that leads them astray.
