While the details about certain other sequels ended up being inconclusive, I stumbled upon more information about the sequel to Pokemon BW.
This game takes place 2 years after the events of the prior games and you play as someone different who lives in a different town. It’s still Unova, but a few changes have been made (ex: new towns) due to some incident.
There will also be some different gym leaders. One of the new revealed gym leaders is a poison type (which is awesome, by the way), although the other is a water type user which makes me wonder if something happened to to Striaton Trio (Could my headcanon about them be true?). Whether this means more badges to get or a whole new set of gym leaders, we don’t know yet.
All I hope for is that this isn’t a totally new game disguised as a sequel. I want to see the old characters again since I really grew attached to all of them.
We shall get our answers when the game is released in Japan on June 23, and later here, in the Fall!
