3DS sales are sad. It probably won't even come close to last year's final quarter numbers. Last year, it started selling 300k+ every week starting on the second week of October. It was selling 100k+ per week in the US and Europe. It's probably is going to have a hard time doing half of that this year. It was a really dumb decision from Nintendo to not launch the NEW 3ds model this year in the west.
Predictions for LT console sales:
PS4: 120M
XB1: 70M
WiiU: 14M
3DS: 60M
Vita: 13M
