If the 3DS is down 5% in its strongest territory by far after the N3DS launch, what does that mean is likely for the west where the sales have been notably weaker for a long time?
it's useless write you prediction.
As i said, OF COURSE 3DS can be down, but said that is IMPOSSIBLE that will be up not have sense.
2020 predictions: NSW 21m, PS5 6m, XSX 4.5m, PS4 9m, XB1 3m
(PS5 and XSX predictions will most likely change after we know enough about them)
