How well do you think Metroid Dread will sell?

The Switch has the best selling game in a lot of franchises, Smash Bros, Zelda, Animal Crossing, soon Mario Kart, Luigi's Mansion, Pikmin, Mario Party, Mario Sports, Fire Emblem, 3D Mario, Xenoblade Chronicles, the third, soon second best selling Pokémon, the second best selling Paper Mario and Kirby.

Why should a new long awaited Metroid game, the first in HD too, not be able to outsell the 2.84 million copies that Metroid Prime sold.
It has everything going for it, it looks great, the reaction to it was overwhelmingly positive thus far, on Amazon it outsold everything else in preorders in Japan, Germany, the UK and the US (didn't look at others).
I see it selling easily over 3mil and up to 4mil, maybe even close to 5mil, but that won't be as easy.

This is pretty much the exact post I was about to make.  If the reviews are good then my prediction is 3+ million.
