It would need one or more great new models, multiple price cuts (down to $200 for the base model at some point) and 7-8 years before its replacement at minimum.
Hitting a low enough pricepoint is the thing that seems least likely to me, because its just not necesarrily in Nintendo's interest to cut the price and keep strongly pushing the hardware by the time its successor is around the corner.
Basicly I don't think its impossible, but currently I don't see it as likely. I do expect it to land closer to 150 mil than 100 mil though (so basicly above 125).
