The Switch version of Breath of the Wild shipped 17.41m by March 31st. Lifetime sales expectations?

Game sales prediction threads should be limited to a single generation. Otherwise, you run into the GTAV problem (that will likely become more common, now that Rockstar has done such a good job with it) where the same game releases on multiple generations. How the hell can we predict sales when we don't know if a game will sell for 5 years or 20?
