When are they gonna change the "theme song" to Serenas new design?

Question

Like when they show all four characters, when are they gonna change it to Serenas new design? Sorry if that was confusing.

Comments

they might change the cinematic in the song to match her new appearance (like how it changed several times during "adventures in unova and beyond" theme)

They just added different Pokemon in randomly.

It was really underwhelming though

Answer 1

Most probably in the theme song of the next Pokemon season. I don't think the theme songs ever change once made. However there might be a chance that they could later on. I don't follow the Japanese anime because they're no fun so I don't know when. I hope that answers your question.
