I was so certain that there'd be something big for the final base roster reveal in Ultimate, after the E3 and August Directs were such crowd-pleasers, and then we got Incineroar. Who's great, I love that he's in the game and I enjoy playing him occasionally, but certainly not what anyone would expect to be saved for last.
And then the same thought process with the first Challenger Pack, with the last character being said to be Ultimate's final character, as well as just the last character for that pack, so it must be something big and special... then it was another Fire Emblem character.
At least this time we know, full stop, that this is the last character for this era of Smash, so there's greater likelihood this will be something special. But so far Sakurai hasn't placed much value on who's saved for last, so nothing's for certain.
What were the orders of reveals for Brawl and Smash 4's base roster? Because Bayonetta got a lot of hype when she was announced, as she was one of the popular ballot options at the time, so it wasn't like they announced, say, Wii Fit Trainer for last.
Bring me XJ9 and a Ghost Zone stage.
