Y'know, there's another possibility to the boxart thing that I haven't seen many people bring up.
The next two characters are being revealed fairly soon. Anyone else after them are just left off the boxart entirely in order to avoid leaks.
I think someone from GameXplain brought it up, when they discussed it, and it got me thinking.
What if the box may not show the final roster,
but who will be revealed next, how many will be revealed, and how soon they will be shown.
Most of the people in the video don’t buy the theory, however they proposed the idea that it was possible that the graphics team only knew who character 68/69 and potentially Ken were in the game and decided to also include them in the box art, which might explain the order in which they were put on the box. However, since they weren’t revealed yet, they ended up removing them from the box art. They said that it may be possible that since they could’ve only really known that Character 69 and Ken were in the game because they were planned to be revealed soon.
I guess it works, on one hand they might indicate that 1 newcomer and 1 echo are being revealed soon since it’s usually on a need to know basis, while on the other hand it also doesn’t indicate them as the final newcomers because they were only given the two other characters that were planned to be shown soon and not beyond that. This also helps with Vergeben’s claims since now all three of the characters he’s leaked so far (Ken, Gen 7 Pokémon, and 2nd SE Character) can fall into this as well.
I think we learned our next newcomer(s) reveal, and that it may come soon. It may be a matter of who will it be.
