Japan - 1.75m
US - 2.2m (judging by 11.5m sell through in US stated by Nintendo)
Europe - 2.2m (usually same as US)
10% for the rest of the world - 620k~
Total - 6.77m sell-through WW
Need to ship 9.68m to beat last year, and 9.45m to not become the lowest selling year for 3DS.
Shipped 7.65m this Q last year.
Based on that sell through, it's hard to see Nintendo shipping anywhere near 9m.
