With what we know now at the moment, I'm not sure if Nintendo will reach their shipment goal for hardware, but it'll likely be close.
Super Smash Bros. Ultimate appears to not only breaking series records and showing why it's one of Nintendo's biggest franchises and the biggest video game crossover we will ever see, but it's also doing its part in moving hardware. We've seen the last couple of weeks that Smash Bros. Ultimate is a significant driver in hardware sales in Japan (not sure how significant it will be in the US and Europe, but it should be great).
Plus, Pokemon Let's Go appears to be holding its own, especially as being mainly a remake of Pokemon Yellow and not a new generation game. The Poke Ball accessory should net some nice additional income for Nintendo, Game Freak, and the Pokemon Company.
Super Mario Party is a surprise hit, as well. While I'm sure most of expected respectable sales for the game, as it's still Mario Party, the game appears to be doing more than it's fair share of appealing new Switch owners. Plus, the Black Friday Joy Con bundle appears to have done wonders. It doesn't hurt that the game itself is considered a well-done, back-to-basics game that brings back old fans who may have fallen out of love with the series.
Then you got the evergreen titles that continue to sell. Hell, even Xenoblade Chronicles 2 has managed to get back into the top 30 of the eshop (US, at least) after being out of the rankings for almost a year.
