Havent seen this discussed anywhere else (otherwise plz delete the threat).
It seems that not only the controllers will feature haptic feedback but also the screen.
This hasnt been shown at all in the switch presentation nor was it a feature in any of the presented games. Is Nintendo holding back something? It could be more convinient to navigate throug the switch OS having haptic feedback. However, we dont know much of switch's OS either.
Edit: It could be just haptic feedback like some sort of vibration. Not necessarily a haptic screen by itself. Not sure what the ign article really says.
