I doubt they had a separate team that made the Spirits battles and had no idea on who would be DLC. Because if that was the case then that means that team went to contact Square Enix to get the rights to use Geno and Mallow without Sakurai's knowledge. Seems like Sakurai would give a look over on what Spirits are being made before they're finalized.
Also making Spirits aren't difficult. They just select the character that closely resembles the Spirit, choose a stage, and apply a certain difficulty. All the hard work is already done with programing the CPU for battles.
This is more proof that you are
talking out your butt uninformed on the topic at hand (mods say I gotta be less sassy now).
First off, it has been confirmed in interviews that a separate team that didn't work on anything BUT Spirits existed. Secondly, yes, Sakurai came in periodically to look at their choices and make some suggestions but BY HIS OWN ADMISSION he was not very involved with the process.
This and you are uninformed on Spirit Battles. In addition to difficulty, stage choice and character choice to represent the Spirit, there are also:
- Stage Modifiers (Lava, Poison, Sticky)
- Battlefield Modifiers (Heavy Winds)
- Item Modifiers (Choosing which items spawn, when they spawn, whether characters start with them or not)
- Character Modifiers (Steel, Big, Tiny, More or Less Damage, More or Less Defense)
- Playstyle Modifiers (Favoring certain moves, prioritizing items, whether they are more aggressive or passive)
- Additional Characters (How many there are, when they appear, whether they are required to be beaten or not)
- Event Modifiers (Random Events, frequency of changes, who do and don't apply to)
- Battle Types (Stock, Timed, Stamina)
There are likely more I have missed, and you know what the best part is? I HAVEN'T EVEN PLAYED ANY SPIRIT MODES! This means I got all this information from basic research, so you've done nothing but played yourself here and...
No it's not, fan rules are not keeping these characters out from being playable. You think Sakurai & Nintendo are looking at this and just say "Dang it, we were going to make this character that was a Spirit/Assist/Mii Costume but these fans are saying it deconfirms them. I guess we'll just drop all the our plans because these fans created the rules for our series."
They don't care what our fan rules are. They are not holding anything back. Sakurai and Nintendo are going to do whatever the hell they want regardless of what the fans think will happen.
And then you defeated your own argument with a post. You can't make this up.
Fine, name a Nintendo character that still available to become a Fighter that currently isn't an Assist Trophy or a Mii Costume.
Right now our deconfirm Nintendo characters are Krystal, Isaac, Midna, Ashley, Takamaru, Waluigi, the entire ARMS series, Dillon, Lyn, Skull Kid, Chibi Robi, Custom Robo, Dixie Kong, Rex & Pyra, Saki, and Viridi.
And THEN you proceed to challenge someone who's defeated your arguments? Okay, I'll bite.

Of course, this is outside projects we don't know of or have little knowledge of.
EDIT: Just realized Town isn't Nintendo, it would be second party like
. Any others I mentioned in that list I apologize, I did my best to research this.
