That's exactly it.
Apparently, they didn't contact the EU teams again for the second pass when they did so for the first one.
We don't know the reason, but Covid might be it.
However it implies that they didn't require assistance from these teams. So they don't need a character that uses French, German, Italian or Spanish.
According to Xander, when they record the characters' names, they have a huge list so they cannot come back and potentially leak who is next or not.
Meaning that, since Min-Min, they didn't get in contact with the European (and Russian) teams.
The only characters that are forced to be voiced in at least French and German are the Pokemon, because their gimmick is saying their names and they have always been localized in Smash since Melee.
tl;dr It only matters for a Pokemon. But not even all Pokemon.
You can have a Pokemon that doesn't scream his name or that has the same name in all countries besides Japan. Such as the legendaries wolves.
TBF, I can see an edge case where Nintendo could add FP2 chants in a future patch, but that feels kinda unlikely given that they were released without it to begin with.
I wouldn't be surprised if Nintendo wanted to record chants for the FP2 characters, but lacking remote work infrastructure (Nintendo's not been the kind of company to rely on Zoom, I assume, before the pandemic. That also might be the case with Bamco / Sakurai) might've prevented that from being recorded at Nintendo's offices,
That + Nintendo's history with secrecy might've made it more trouble than its worth from Nintendo's PoV - especially since we're talking something pretty minor that only comes up on average once per match at most. It's pretty difficult to get the crowd to cheer to begin with:
while the reasons are not entirely known:
... common trends include having high damage, the start of the match after the announcer gives the "GO!" signal, and doing something significant, such as KOing multiple opponents at once, or falling behind considerably during the course of a match.
Anecdotally, I've heard it most when I've been at high damage and used Limit Blade Beam to help secure my recovery (with the Beam hitting my opponent away from the edge or at least forcing a shield).
Btw I’m wondering which characters have a Korean voice track?
Well, here they are. (I believe some Korean chants are the same as the Japanese, probably the FP2 characters, but we'll have to see.)
(Damnit, I'm a bit sad that SSBU doesn't have commentator packs. Because the most memorable Korean casters are nuts and I'd love to see this kind of insanity included as optional announcers) (
Volume warning):
And yes, this also goes for other games like LoL, where the memorable Korean casters are equally hype-inducing.
