I disagree with your prediction for reasons that I explained already in another thread.
Let me say this, the only market that will be affected by this (potentially) is Japan. Smash on 3ds in western markets is going to do significantly less then smash on wiiU.
Predictions for LT console sales:
PS4: 120M
XB1: 70M
WiiU: 14M
3DS: 60M
Vita: 13M
