A person of culture, I see.
You are missing a few- but yes. I have the exact same opinion.
Smash Director's cut.
I think it will be 2023, with the Switch pro.
Rollback Netcode. Serial DLC Story Mode. Boss Rush.
Seven more echoes (including Impa, Octoling, Dixie)
Five-Ten new base characters (I'm gonna guess Dragaux, Isaac, Another Pokemon/Maybe Finally Zelda [hoping for all four champs]/ A New Mario character, but probably Captain Toad [after the sequel is released] and another Retro Nintendo character are givens, plus one more third party, which I will think to be Bomberman, or someone from Bamco, like Nightmare or Agumon).
Then 2 more rounds of DLC. This will be from all the companies that reached out to Sakurai for inclusion, as well as new ideas Sakurai has over vacation. And a desire to improve upon his work.
choice.
I think it a bit more simple:
6 new comers; splatoon 3 character (maybe new octoling/villain incarnation), Ring Fit Trainer and a gen 8 Pokémon to represent late switch era. As fan requested character, Bandana Waddle Dee. From third parties 2 characters; the big addition is Leon/Jill from Resident Evil (like Steve/Alex, one is an alt from other) and an AT promotion; Akira Yuki from Virtua Fighter (full VF moveset translated to Smash, has a low poly alt similar to the actual AT). You would still need to buy FP1/2 DLC characters individually.
new stages using assets from switch games; Splatoon 3, Pokémon S/S, Zelda BOTW2, Ring Fit, Mario Kart 9, MH Rise plus a Resident Evil and Virtua Fighter stage.
There would be a post-game WoL area with 4 new bosses; Tabuu (fight similar to Brawl but new attacks), Porky (the same as Brawl), Dr Eggman (similary to final Sonic games) and Magnamalo (from MH Rise).
8 new AT; 4 returning from previous games (Infantry & Tanks, Kat & Ana, Saki Akamiya and Ray MKIII) and 4 new ones (Arthur from GnG, Magnamalo, Solaire from Dark Souls and a new one from a popular third party like Among Us crew or something smilar). They also add 4/5 new gen 8 Pokémon.
Around 150 new tracks, the majority from 2020-23 switch games. Not many new remixes. Around 90-100 new spirits (most of them will be included in the new WoL section).
the only new mode is create your own target smash, same parts as stage builder (maybe a few new more included) and share online with anyone. You can set some conditions like time or beat with X character.
4 new mii costumes; Astral Chains twins and 2 more from late switch era titles.
After, they plan 6 DLC characters, 1 standalone (Chun-Li from Street Fighter) and the rest as a new FP (Xenoblade 3 protagonist, Crash, Master Chief, Lara Croft and a future swtich title character like next FE lol). Each of this new FP will include stage, music and spirit board. Mii costume waves from Crash and MC will be from Sony (Nathan Drake, Kratos, Alloy, Ratchet & Clank and Sackboy) and Microsoft characters (Marcus, Joanna Dark, Conker, Fulgore and Ori).
