So I have a theory I want to share. This theory could be kind of a stretch since it does kind of involve going against Official Statements, but I have my reasons why
---------------------
I have a theory on how despite Sakurai saying we only have one character left (CP11),
that we can still get a Bonus Fighter of Some kind.
It's pretty simple theory, They are going to make the
Presence of a Bonus Fighter seem like a "Recent Development" due to the Popularity of Fighter Pass 2.
Pretty much, While Internally the avenue of there being a Bonus Fighter was already a known thing among the Developers, In Public, they are going to have a Bonus Fighter for FP2 as a Direct Result of the response to Fighter Pass 2. Pretty Much Sakurai will "Make an Exception" to FP2 being it because the Support was so great. This will do certain things
-It's Really good PR, having the Fans be the reason that we get more content than intially expected. People love that
-It Adds more Value to the Fighter Pass 2. This would especially be useful as FP2 Concludes near the Holiday season (especially if there is Bonus in line). People will be getting more Switches, which means more Copies of Smash sold, and by Proxy more DLC
-Even if Separate, I Imagine if it's a characters many people want, It will sell good amount as Individual DLC, enough to be considered worth developing after the Initial FP2
I understand that Sakurai has been adamant about the prospect of there only being the 6 Fighters in FP2 before the continuous Development ends, However there's been things said in the past, that if we figure the usual Internal Development of characters, can't really be true
Masahiro Sakurai Explains Why Mewtwo Isn't Paid DLC in Smash Bros. - Nintendo Life
This Article had Sakurai saying that no Paid DLC was in Development. However Considering how quick they were able to Make Lucas, Roy, and Ryu after the Release of Ryu (Including Showing off Lucas, when Mewtwo got his Trailer), and also the avenue of Data relating to Addition of Bayonetta in the update of Mewtwo's Release, there's no way in that short timespan they went from No Planned DLC to being able to so quickly show off some of the further DLC we got
And the Whole Bayonetta situation is a different matter entirely. While I'm sure Bayonetta actually did well on the Ballot, There Early Data placements as well as general timeline of negotiating and developing characters doesn't allow Bayonetta to have been directly chosen from the Ballot
So these situations have shown to have had somewhat of a Plot twist after the fact. What I will say is that I think Sakurai has been more adamant about there being only 1 character currently than any statement made in the Past that seemed to have been Contradicted. That's why I still think this theory is kind of a stretch because Sakuai's statements have been especially strong this time
For why a Bonus Fighter wasn't intially shown at the Beginning, the whole point is that it's a Bonus, which means it doesn't take priority over the Development of the Main content, which is Fighter Pass 2.
If there were to be a Bonus character, I Imagine since it wasn't apart of the initial FP2, it's one that Nintendo has full access to, as well as not needing the extra Supplements like Music and Stages. I have a certain character in mind
