At the end of the day, I just don't trust Nintendo to pick fan-demanded Nintendo characters for DLC, as awkward as that sounds. Granted, sometimes the two overlap, like Min Min and Pythra.
And I mean, on their end, why wouldn't they approach it like this? It not only works as advertising(I believe I saw ARMs went up like 300k in sales since Min Min came out), but it also helps Ultimate to feel less dated, which, like I brought up the other night, Ultimate launched with 3 Switch-era stages, and 0 Switch-era characters. We now have 6 Switch-era stages and 4 Switch-era characters.
I'm not opposed to the idea, it's just, looking at this strictly from Nintendo's angle, they seem to have their priorities laid out.
