I'd also bet on around 8m, but partially because while the shipment ratios may have changed, it's likely that the shipment amounts have increased pretty heavily. We know what they've increased by in Japan but the US has seen quite a big stock boost too, likely higher than that in Japan (relatively speaking).
I'm guessing something like 7.3-7.5m WW will be announced at their earnings report in 2 weeks for the total through September.
ah, just did a guess that is basically that too, 7.2M for the low end and 7.5 for the high
Very impressive numbers either way
