a threat no, but it can sell a lot and have its place, new generations of kids have no idea what a Kinect or Wii is , they dont have any concept of that, so something like this is completely new for them and probably fun, and obviously this is perfect for parents who actually remember the motion gaming era
its a trend like any other, it will comback eventually, maybe with this shitbox or in an other way, Nintendo already has the camera, Sony and Ms with their experience can shit out something quickly and easily if the trend really comeback
