Europe + Japan FW = 3.2m
That means FW in the US would have to be under 800k for the game to sell under 4m WW FW.
My prediction: 5m+ WW for Week 1, 10m+ by Jan 1st, 2017
For Sold? By end of Nov i bet its close to 7mil sold ww
Japan: 2.3mil (rounded it up) [2 weeks]
Europe: 1.5mil [1week]
NoA: No less than 3mil
Thats 7mil. Its going to be over 13mil sold WW by years end imo. 15mil+ shipped WW
