The health and wellness industry isn't exactly untapped fertile ground. There's a shitton of products and services in that market already, from companies who've specialized in it for years. It sounds to me like trading one oversaturated market (casual gaming) for another.
Given how next to none of the Wii Sports/Wii Fit crowd has shifted to the WiiU, in large part because of how unappealing and poorly marketed it is as a product, I don't have much confidence in this initiative right now. We'll need to see more about it before I'm convinced.
Also, I find it hilarious that so many people are going "tl:dr fuck Gamespot" given all the even worse hack articles and biased shit that gets threads on this site everyday. :p
