There's that and the fact that the third party stuff not only has a lot more evidence but also has longevity. Like I've told the thread many, many times, Waluigi is the only first party character that's ever really come up in insider circles and everyone has heard him at some point since 2018. I've also explained why Waluigi is the perfect first party character to leak because for so much of the fanbase, he's literally unbelievable to the point that even until very recently a vast majority of the Waluigi fanbase had packed things up and figured it wasn't going to happen. Literally in the past couple of weeks, however, first party content has gotten an enormous boon not only because the no promotion fan rule is dead but new stuff has come up that heavily conflicts with Season 2 being only 5 more characters.
I mention this because several first party characters have very loyal fanbases and a quite a number of people have messaged me in the past year and a half about first party content. Each time it's happened, I've said "sorry, first party stuff has rarely come up" and I feel bad because I was telling the truth but it probably squashed the enthusiasm of a number of people. One is the Dixie fanbase. I've gotten some very heartfelt messages from Dixie fans (including a few people I've known since the Brawl days) because, like the Geno fanbase, she's an evergreen character that's the last big pick for a good number of "Boomers." I'm very happy things have seemingly turned around and I hope I didn't extinguish anyone's hope solely based on my own reports.
