Give me compelling reasons/proofs why Wii sports or Wii Fit won't be huge system sellers again for WiiU

- Wii Fit Plus, Wii Sport Resort but also all the Just Dance annual iterrations, Zumba Fitness, Kinect games... all sold or keep selling really well even in a very recent past.

Most casual gamers have no brand loyality. So...

- casual sport/fitness gamers who cared about graphics probably have moved on to Sports Champions and Kinect Sports a while ago

- casual sport/fitness gamers who don't care about graphics will stay with their Wii for some years. If they finally decide to upgrade, they have several options and 360+Kinect is much cheaper than a WiiU

So I guess AC NL, Tomodatchi 3DS and future MK games are doomed too then... Except they are not.
