So has anyone considered the plausibility of there being an underlying method of reveals?
I mean, let's face it. It's a little bit crazy that we have all Mario characters revealed. I mean, granted, I get that they aren't exactly unexpected, but that was a lot of reveals devoted to Mario...and our first Veteran Series Newcomer reveal was from Mario...
I call this the "Series Completion" Theory. Basically, any veteran series that is to receive a newcomer, will receive said newcomer once their series is complete. Hence why Mario got their newbie, and why Dixie couldn't have been revealed for Tropical Freeze...Diddy wasn't revealed yet.
However, now Donkey Kong, Kid Icarus...they're both done, and have high chances of getting a Newcomer. There isn't anything refuting it just yet, but it's just something to consider until proven otherwise.
