Its become apparent that the twins own the casual game market today. So it makes sense if Nintendo gambles again and tries to get the smartphone crowd. I just don't think that it will involve wearable sensors. How is that going to work to tap into smartphones? You'll still be swiping away just without a screen. Not to mention holding the phone. It won't work with wearable devices unless you're wearing 10 rings or 2 gloves. Then it gets too complicated.
