Where do you get the idea that
![Corrin :ultcorrin: :ultcorrin:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
and
![Byleth :ultbyleth: :ultbyleth:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
were planned before the game was announced? You're just guessing and throwing it around as a factright? In any case
![Corrin :ultcorrin: :ultcorrin:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
and
![Piranha Plant :ultpiranha: :ultpiranha:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
were released so long ago they're irrelevant to my point. The trend is just for
![Byleth :ultbyleth: :ultbyleth:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
and
![Min Min :ultminmin :ultminmin](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
. I think you're talking out of your ass when it comes to
![Byleth :ultbyleth: :ultbyleth:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
but you're right about
![Min Min :ultminmin :ultminmin](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
being planned long ago however that's the point. After getting the DLC they wanted out of the way, Nintendo is going back and adding the first party characters that should have been in the game and I believe that trend is going to continue with the IPs I just named. I don't know what criteria you're using to say Astral Chain and SWSH is out, probably spirit board events(which Paper Mario would fall into as well), which is stupid as hell as
![Min Min :ultminmin :ultminmin](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
proves spirits doesn't matter and
![Byleth :ultbyleth: :ultbyleth:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
shows Spirit Board events don't really matter either.
