That's Autumn 2019 in Australia, Spring everywhere else.
After hiding away for a little bit, Yoshi on the Switch has a new name (which was leaked before but alas) – Yoshi’s Crafted World.

No seperate trailer, but here’s some footage from the Direct;
Or in the office, we won't judge
Definitively done with the Wii U now.
