Well, that coverage at the Nintendo Direct with over 500k viewers on the YT stream + another 500k on other platforms must of definitely shed light on the game among the Nintendo crowd.
It's released in July, a rather stacked month for Switch software, but it should hold on its own. Nintendo is renown for their platforming games (Mario, DK, Kirby, Yoshi...) so while this game is harder than their average platformers, it's still a genre that is most popular with the Nintendo crowd. I feel like this game will sell really well, at least 1 million units honestly. It's such a perfect fit. Meanwhile, I see the Xbone version doing half of whatever the Switch one does.
