Well, I can guarantee it will sell at least ONE copy! :D
But I think it's going to sell a TON!
And I mean TONS!
Maybe even an entire ONE MILLION COPIES!
I can't even count that high in under 277 hours.
It would take 259,196 Switch cartridges to make a ton. Selling tons would mean at least 518,392 copies. Of course, all physical. Seems pretty likely that it will sell tons.
