Typically after a mini direct, a full direct follows in 3-4 weeks.
Honestly, I don't think they need to announce anything super new. Probably an update on the next Mobile title, Pokémon dev footage, a mini trailer for Metroid, Bayonetta 3 footage, Fire Emblem trailer, Yoshi full trailer 7 release date, Smash Bros port with additional characters and DLC, and Pikmin 4 trailer.
