Uh, I'll try. If you assume none of the mystery games were announced at the time Emily posted (so they're not Luigi's Mansion 3 or Animal Crossing), my best guesses would be:
1. Mystery game #1 - Astral Chain
2. Mystery game #2 - Link's Awakening
3. Mystery game #3 - Super Mario Maker 2
4. Mystery game #4 - ????
5. eShop game #1 - Tetris 99
6. Wii U port #1 (2013 title) - Pikmin 3 (judging by Zell's leaks)
7. eShop game #2 - BoxBoy! + BoxGirl!
8. eShop game #3 - Cadence of Hyrule
9. New Labo Kit - Labo VR
Assuming this is right, there's really only one game Emily hinted at that's totally unaccounted for. I doubt that it's BotW, since there's no indication that it was ever supposed to be a 2019 title, so it probably hasn't been announced at all yet, and has presumably been pushed to 2020.
