Just calling what should be the standard controller the "pro controller" clearly demonstrates the Nintendo mindset that it's target audience is the casual gamer.
OT Not sure about that concept design. For it to make sense the screen would have to be a lot smaller than the current GP screen for this pro controller based design to make ergonomic sense. And once a screen gets too small then it becomes functionally compromised. I think Nintendo wanted a touchscreen controller, they figured out the ideal size (screen capacity vs cost vs ergonomics) and then built a controller around their optimised screen size. For all one can argue that the gamepad was a negative factor for Wii U and contributed to its lack of success, design-wise it's probably the best you could get having a touchscreen, with buttons and thumbsticks, that does not look like a PSVita.
