Being able to sell 75-80M handheld devices per generation is enough to warrant another handheld. The market is dramatically smaller, but Nintendo definetly won't overlook these 75 million people who still want handhelds though.
Predictions for LT console sales:
PS4: 120M
XB1: 70M
WiiU: 14M
3DS: 60M
Vita: 13M
