Looks like Apple is hiring a bunch of people from the health/fitness fields and work on an "iWatch" which has biometric sensors:

"Reports have suggested that Apple's smart watch project, the iWatch, could focus heavily on health sensors and biometrics, possibly including features like a pedometer and a heart rate monitor. Apple's multitude of hires in the health field does suggest, however, that the company could include even more advanced sensor technology in the iWatch or in a future product.
With the addition of O'Reilly, Apple has now hired employees with expertise in pulse oximetry, vasculature visualization (vein finding), non-invasive glucose monitoring, blood chemistry monitoring via microneedle, heart/breath rate monitoring, and fitness. Notably, several hires have also had experience with low-profile, non-invasive biosensor devices. "
Not sure if this field is really going to be the blue ocean Nintendo thinks. It's not a bad play I guess to liberate ideas like Wii Fit/Brain Training from being tied to a hardware platform if casuals don't want to buy an entire game platform just to have those experiences, but if Apple is in the mix, honestly I can't imagine Nintendo being able to compete.
What's supposed to be the hook here? That Nintendo's version is non-wearable? Doesn't seem like a very compelling difference to me.
