The amount that PS4 outsold WiiU by is kinda irrelevant. If the PS4 sold 500K and the WiiU sold 143K, it doesn't mean the WiiU sold bad, it just means the PS4 sold extremely well.
Nintendo shouldn't be panicking that the PS4 outsold the WiiU by 3.5x. They should be concerned that it only sold 42k, making 3.5x easily achievable
