All right, here's what I predict.
*New info on some games we already know, including the rumored Magalor Epilouge mode in Kirby's Return to Dream Land Deluxe, new info on Pikmin 4, and the release dates for Legend of Zelda: Tears of the Kingdom and Advance Wars 1+2 Re-Boot Camp.
*A new Mario Baseball game, we have new installments of Tennis, Golf and Strikers already, so I think a new Baseball is a given.
*Perhaps the next trailer for the Super Mario Bros. movie, they had two Direct focused on those trailers, so I wouldn't be surprised if this is where the third one drops.
*Wild card, a sequel to Super Mario Odyssey for the second half of the year.
*Wave 4 of the Mario Kart 8 Deluxe Booster Course Pass, or at least a tiny piece of it.
*A new port of a classic game, I'm gonna guess Star Fox Zero.
*Wave 2 of the Fire Emblem Engage DLC.
*New Xenoblade Chronicles 3 DLC.
*New Splatoon 3 DLC.
*From SEGA, new information on the first free update for Sonic Frontiers.
*From Capcom, a new compilation game.
*From Bandai Namco, something related to Pac-Man.
I also believe the next Pokemon Presents will be later in the month, so I'm gonna make my predictions for that too.
*Scarlet and Violet DLC, we know it's coming.
*Detective Pikachu 1 port, to prepare for Detective Pikachu 2.
*Details on the next season of Pokemon Go, among other updates to mobile games.
*Remake of Pokemon Mystery Dungeon Explorers.
*Wild card, Let's Go Pikachu and Eevee Expansion Pass, to celebrate 5th anniversary of the game's release.
