Smash Ultimate is doing amazingly well. I normally thought of this series as being front loaded. Right now it is the Switch's top selling evergreen title both overall sales and in weekly sales (in Japan). Smash is definitely doing better than I ever thought it would. Zelda is also doing surprisingly well. It is above Splatoon 2 for another week. It is only low in the charts, because so many titles were released this week.
Hopefully we'll continue to get data every week, even if Media Create won't be the one providing it. I'm going to stay optimistic.
