- Pitfall
- Smoke Ball
- Spring
- Unira

We have also technically not seen 6 other items from previous Smash games, which I doubt will return.
There are currently 36 revealed Pokeball Pokemon in Ultimate, and we were promised more than Smash 4. (40) We have not yet seen:
- Moltres
- Togepi
- Gardevoir
- Arceus
- Dedenne
- Fennekin

...in addition to 30 other Pokemon from past Smash games, which I don't expect to return.
There are currently 40 revealed assist trophies in Smash Ultimate, and we were promised "over 50." We have not yet seen:
- Devil
- Infantry and Tanks
- Kat and Ana
- Lakitu and Spinies
- Saki Amamiya
- Shadow the Hedgehog
- Tingle
- Chain Chomp
- Dillon
- Elec Man
- Magnus
- Nightmare
- Phosphora
- Sablé Prince
- Skull Kid
...in addition to 7 removed from Brawl to 4 because the characters had grown irrelevant, like Isaac.
In all 3 cases, it is a safe bet that the returning content more than makes up the deficit. Additionally, more than a couple additional new entries would put us over the blog schedule, for what that's worth.
Maybe Sakurai really is getting rid of the Home Run Bat and Freezie, Gardevoir and Togepi, and Lakitu and Kat/Ana. Or maybe that's really dumb and the last direct is focusing on all the single player and online content,
just as the last one focused on all the items/Pokemon/Assist Trophies.
