While I do love a standard controller, in a way I'm glad Nintendo are shaking things up. If the console can output beautiful looking games that play well, then I'm good. Nintendo has never done things by the book, and that's come around to bite them in the ass, but it's also worked out for them.
As much as we all want it, we should never expect Nintendo to not have a crazy new controller. It's likely that there'll be a standard controller to buy at a later date.
The Wii U gamepad wasn't the issue with the console. There was a lot more that went wrong with it. We can't live in a world where we can play all of our Nintendo games on one console without having some form of touch controls. It just doesn't work for DS & 3DS games. What's important now is the way Nintendo reveal this thing. They need to make things perfectly clear, unlike the Wii U launch.
Don't solely focus on the control, Nintendo.
