Wow, I missed a bit.
Honestly I had no idea what
is.
I agree that the Dee probably stands the best chance at DLC from Nintendo. We only got 1/4 from Nintendo last time, so with 5 newcomers I think we’ll have at least 2 Nintendo reps. Bandana Dee would be the first, but I do think we’ll get a Pokémon from the newest generation as well (Gen 8).
3rd party is tough but I think a Square character seems likely, and with Piranha Plant being the new Mario character, I think Geno will be scrapped in favor of Dragon Quest. Dragon Quest has a huge history with Nintendo, even having crossovers with Mario and the generic Slime seems to be more plausible due to Piranha Plant.
After Square, I would guess Minecraft, a title that is loved around the world and by Sakurai himself. Plus Microsoft said Nintendo could use their characters, so while some see this as Banjo, I’d say Steve being a more recognizable character from a more recent series means he’ll gain the spot. Plus he’s now been on 3 Nintendo systems, has his own custom 3DS and Mario skins, and brought cross play between Microsoft and Nintendo. Everything seems to line up for him perfectly.
The final is probably the hardest to say, but it’s either one of the two Ubisoft mascots or (here.. we go), probably an Undertale character. To give out points for both
Ubisoft: Rayman or Rabbids
1) Rayman Trophy in Wii U
2) Rayman voted highly on ballot after ArtsyOmni Leak
3) Rabbids + Mario Crossover
4) Rayman Legends port on Switch
5) Rabbids + Mario 2 set to release along with Rayman 4
6) Star Link has Star Fox content due to Nintendo going to Ubisoft
7) Rayman in Smash clone Brawlhalla
8) Mario + Rabbids Just Dance Bonus
Undertale Character: Sans
1) Sakurai confirmed that he likes Undertale
2) Undertale is huge in Japan
3) Released in 2016, same time as Smash development plans
4) Now on Switch
5) Toby’s newest game hints at it with a comment about being in Smash
