I feel that the reason why Sakurai picks certain characters comes down to something similar to Robin...”I could visualize exactly how he could play as soon as I saw the character”.
If the character is suggested by a fan, and the ideas that come with it immediately remove the character from their home game context (something Smash has effectively not done yet to a severe extent), or throw random references into a moveset, it’s already not promising imho.
Saying Daisy could, “use plant based moves or flower moves” betrays what she is as a character. She has never commanded the power of nature, never used vines to attack people, etc... Viridi or a Grass type Pokémon would be more fitting for that type of moveset.
I myself have never been a huge fan of Daisy, but hats not why I don’t expect her. There are a number of reasons I don’t expect her, but those are also reasons why I don’t really expect any Mario spin-off character to be in Smash. There are “big” characters from other series I would really like to see, so I would honestly prefer to not see character from the “B team” of Mario. I could see Captain Toad because he has his own game and now a port.
If any other Mario character from a spin-off had to get in I would prefer Waluigi just because of the hilarity. For my own feelings on Mario (It’s always my favorite...I grew up with it and put an unhealthy amount of hours into various Mario games, made my friends incredibly salty about Mario Kart, Mario Party, etc), I just don’t think it needs to keep getting more characters. The current roster is wonderful in my humble opinion.
Despite their popularity, Daisy, Waluigi, Birdo, etc, have always been the supporting cast. In a game like Smash, a game that collects the most notable characters from their respective rosters, we’re gonna start taking from a supporting cast before we had main characters from others?
Uh, please pick from series that could give me something cool from a smaller cast. Gimme Dixie or Funky. Gimme Elma or Rex. Gimme Viridi or Medusa, or somebody that comes from somewhere I hadn’t expected.

As a side note, it occurred to me the other day that I didn’t expect half the roster of Wii U, yet it’s my favorite roster by far. I have wants, such as Rex and Pyra, Decidueye, and Spring Man. But i’m gonna fall in love with whoever gets into Smash Switch, so I think for the most part i’m along for the ride.
Then again I DID get like at least 5 correct guesses from the last roster and was super hyped. Either way, I like Smash, enjoy Smash, and play a lot of Smash. So, as long as it’s something interesting, i’m all for it!
