After reading more and sleeping on it, I think this Quality of Life stuff could be a side business, alternate revenue stream, something that can still be directly related to videogames, but doesn't have to be.
Remember Nintendo had those patents for an exercise bike and I think a Pilates ball like attachment that correlates to things happening on the screen. So, games like Wii Fit, Wii Relax (Vitality Sensor) & Brain Age should be part of the QoL platform.
If that is the case, and Nintendo has an all new department that focuses specifically on this, then I see no problem. That could also include specialized games & devices directed at rehabilitation.
