I think Smash will contribute, but I don't see many rushing out "I'm buying a Switch now that Smash is out!" - more like "Ah, here's Smash Brothers, that'll be a good game in my library" as it is more of a novelty title that a small bubble of people has decided is some kind of great competitive grail... similar to the Metroid bubble - both of whom consist almost entirely of existing Switch owners.
The real title that will muscle in the sales is Pokemon. Millions and millions of Pokemon fanatics are still without Switches. I also think people are taking the "Bah Indie games!!!!" thing far more lightly than they should. A gaming console/portable console that can play Indie games holds a much larger appeal than many are considering; I look at my kids and their friends, and that's what they want a Switch for.
I describe myself as a little dose of toxic masculinity.
