Nintendo made the WiiU gamepad because they didnt have a better idea - opinion

[AIAS]

It is interesting you say this, as I had this feeling for quite some time. I  reckon Nintendo & Co have had the idea of a "dual screen in 3D" concept for quite some time and have been evolving it in different models. Hence after Virtual boy which was the original thema came the DS, the 3DS and now the WiiU. The Wii was completely original as a concept.

 

I have a feeling that they may have reached their limits in innovation, since that original idea has maxed out. Of course the Gamepad coincided with the rise of a tablet as a device following us around at home.
