Except, and I mean no offense by this, but as we've seen countless times before; THE SMASH AUDIENCE IS FICKLE and there is no universally wanted character that will be loved by everybody. Like seriously it happened 2 days ago with a ton of people bandwagonning onto KOS-MOS, it'll happen again. If a Bravely character eventually starts looking likely, I guarantee you people will say "Oh, this franchise is awesome and I've wanted BLANK in Smash for a long time".
And besides, I'm not arguing that a Bravely character is "likely"; I'm arguing that they have a good enough shot to warrant some decent discussion. In terms of Square reps, Sora makes the most sense (technically Disney) in terms of popularity; followed by 2B, and then maybe Bob and Bub. But that's not to say a Bravely/Geno is impossible.
The most discussed Square Enix character on this site is Geno, a relatively niche character from a spin-off (that doesn't even have a huge presence within it's own franchise), not to mention the lack of bigger playable characters like Toad/King Boo/Waluigi. His call to fame was literally a bandwagon because of a Newgrounds video, and his fanbase was nearly dead back in Smash 4 but because Sakurai literally talked about him seriously, people started supporting him way more .
So in the end, I fail to see how a Bravely rep is that much more unlikely then Geno, and I think the series warrants some more serious discussion on this site.
Chances are that neither Geno nor a Bravely character will end up getting in; but that shouldn't stop discussion on either of them.
