I think next year we will get the next 3D Mario game, whatever the new Next Level Games is (probably Luigi Mansion 4), Kirby, Mario Kart DLC from your none confirmed list. I do not think we will see Smash other than a possible Switch 2 edition or Splatoon 4. I think most the Splatoon team is work on Raiders and the Splatoon team is also apart of the Animal Crossing team and I would guess that takes priority. Now that I mention it, I do wonder if 2027 could be Animal Crossings year, If not 2027 it'll be 2028. I think we will also get Mercury Steam's Metriod 6 in 2027. I am sure there will be a few other smaller surprises, I know there is a rumor for a Wario game.
Overall 2027 is looking like a fantastic year for Nintendo fans.
