Nintendo works on a reversed paradigm. All companies work on both simultaneously, the visual and the gameplay, but one takes center stage in a certain paradigm.
Also, the experience of the player changes from one to the other. While HD and old systems strived for immersion, Nintendo is now trying to do the opposite. If you want to predict what Nintendo will do next you should ask yourself first: Am I having this idea because it's immersive?
If your answer is yes, you probably got it wrong.
Maybe not the technology itself but certainly its implementation and intended use. Nintendo will create products that attach people to their lives and helps them, instead of immersing them in escapism. Of course there will always be aspects of both in certain games, but the latter won't be the focus and probably nearly nothing will be sacrificed on its behalf during the design process of the system. The priority is squarely at engagement, not immersion.
