Handhelds are dying in the west. That's a fact. Compare 3DS US sales and Europe sales with their previous handhelds and you will realise that the only place in the world that the 3DS is performing well is in Japan. Without Japan, it would be considered a flop by Nintendo and any sane person for a Nintendo handheld.
Predictions for LT console sales:
PS4: 120M
XB1: 70M
WiiU: 14M
3DS: 60M
Vita: 13M
