And so I guess the series might miss an anniversary tweet, if it's new to Smash. Because the tweets were certainly not a factor in choosing the characters. They're just a nice little acknowledgement of the occasion.I know they never really have, but this isn't about a reveal coinciding with an anniversary or anything
It's just that a series getting into Smash Ultimate has literally never missed Sakurai's anniversary tweets so far, and it seems unlikely that they'd go into '22.
I'm not sure if you realize, but this is literally creating a new rule on the spot. "If a character can't be acknowledged by an anniversary tweet due to timing, they probably weren't chosen", or something to that effect.
And it's funny because it really does prove that Sakurai can't do anything without someone reading into it as some sort of Smash hint.
