My prediction on Era:
If Nintendo gives PR I expect ~2.5M global 2/3 day opening, and sell-through by Dec to be at 5-7M. Q3 shipments of 7-9M. LTD crawls to like 10.5-11M (don't expect legs to hold out past launch).
My prediction was ~2.5M sell-through for the launch weekend. With 3M shipped, I guess it depends on the digital share.
Possible scenario:
40% Digital = 1,200,000
60% Physical @ 70% sell through =1,260,000
Total sell-through = 2,460,000
Two separate variables above to tinker with, so hard to pin-point a real number.
I think it'll keep burning hot this holiday season and go over 5M shipped (another ~1M for black Friday and 1-2M in December), but tank after the holidays. Probably end at 8-10M in the end.
