I can't help but have a some bad feeling about that "followed by a brief message from M. Sakurai".
I don't know why.
Maybe that's "just" slightly bad news like delayed characters (FP2 ending in 2022) because of the pandemic, but I'm already thinking about really bad news like Sakurai having health issues or announcing his retirement for whatever reason.
Well, at least we'll know who the next character is and their presentation will probably be released later, like one day or two before the release.
I also don't think Sakurai will present the character himself this time, not sure how that'd be done though.
