I think some of possible wii u buyers didnt buy cos they think gamepad is not a controller, is an undefined mix of tablet, and also seems unconfortable.
If they make gamepad look like a controller with a screen, it should help. mainly if the battery last longer, it weights less and cost less.
they should shrink the screen, get rid of empties spaces on gamepad, and shape it more like a controller. bring it along with a 50$ price drop, win win.
