Lifetime... bit early to predict that I think. There is a lot of unknowns still.
Right now, assuming 3DS gets no 2018 support and NS gets 100% of Nintendo's focus by years-end, I would peg this at up to 30MM to 50MM. That is also assuming pricing remains similar to it is now and the online service is also relatively expensive since they've been pricing everything else relatively expensive (accessories, 1-2-Switch, etc).
I'll definitely revisit this topic in June when VC, online service pricing, E3 (future games support), etc have all been announced to the world. Plus, by then we'll see its lasting selling power to the masses.
