Last year it was 5'7M from Nov 20 - Dec 31 if i remember correctly, so they basically did the same as last year. Knowing that PS4 did more during BF last year in USA than this year, could mean PS4 did better in December this year in USA, or maybe, it just simply did better in Europe or rest of the world....
Probably Europe, as sales were lagging behind there throughout the year.
