The February Directs on Switch have normally had a good number of Nintendo-published reveals - 2019 had Super Mario Maker 2 as the opener and Astral Chain and Link's Awakening to close, with stuff like Tetris 99 and the first footage for Dragon Quest XI S, all as 2019 titles. Fire Emblem got its July release date in that Direct, as did Marvel Ultimate Alliance 3, both of which had previously been announced. Like this year, Nintendo had already tweeted out the release date for a March release (Yoshi's Crafted World that year).
Last year's was packed with reveals, though the first half release schedule was fairly empty before that: Splatoon 3 and Triangle Strategy were announced for 2022; Miitopia, Mario Golf, DC Superheroes Girls, and Skyward Sword HD were announced for the 2021 slate and all launched by mid July. Detective Club had an international release confirmed for May.
Difficult to know what approach Nintendo take this year in terms of the number of reveals. I'd honestly expect at least 3: Everybody Switch, new Fire Emblem, and one out of Metroid Prime HD, Xenoblade 3, or a Wild Card. Release dates for Advance Wars (April) and Splatoon 3 (June/July), pretty obviously.
I guess it depends on how confident Nintendo are on second half 2022 games and whether they want to start showing stuff for 2023 just yet; Splatoon 3's reveal last year may well have been down to the need to recruit staff for the game so I'm not sure how much we can read into that.
