To compile, we have these leaked/logical (but not confirmed) announcements, not a personal prediction, just to put everything rumored and announced together.
- Mario Kart DLC (99.9% confirmed).
- Maybe Zelda TOTK DLC
- Another look at Mario Rabbids DLC with Rayman (Maybe)
- A new 2D Mario game ("leaked")
- F Zero Remake ("leaked")
- Paper Mario TTYD ("leaked")
- DK Game (rumored)
- Metroid HD/Prime 4 (Rumored/Logical)
- Fashion Dreamer (very likely)
- Pikmin 4 (99.9% confirmed)
- 1-2 Everybody (If the game is as bad as it seems, it might not even appear)
- Mario & Sonic 2024 (Logical)
- Chrono Trigger or SMRPG ("leaked")
- Dragon Quest 3 remake (rumored)
- Dragon Quest Monster (logical, because it was announced as a 25th anniversary celebration, so it should be released this year)
- Lara Croft Collection (logical)
- SO2 Remake (Leaked)
- Persona 3 (Leaked)
- Persona 5 T (logical)
- The new Sonic game (Logical)
- Prince of Persia (Logical)
- Mortal Kombat 1 (Very logical)
- Transphobe Legacy (Logical)

- Any of the 5 games Level 5 has prepared. We will probably see Decapolice and Fantasy Life. I wouldn't be surprised to see Inazuma Eleven either. Layton I think not, it will go to 2024, in my opinion.
And of course, HK Silksong...
.
Even if only half of it is shown, I think we're looking at a pretty solid Direct, in my opinion.
