There are VERY IMPORTANT news in relation to this topic.
An important French youtuber named Saikyo Devin spoke yesterday with the great French animator SANDA.
This animator has participated in Boruto, Jojo, One Piece and the remake of Dragon Quest Dai.
I was watching the interview live and he talked about very interesting things related to these series and the animation process.
The important thing is that the youtuber commit what Masaki Sato said many months ago when they asked him at a French event for the animated continuation of Super in which he said he did not know if it would be a series or a movie.
SANDA responds that a continuation of the series is already in production but that he cannot give more information because he does not participate and does not know more.
SANDA claims TOEI productions have changed and now they set things up as much longer as Dragon Quest Dai.
This is not a rumor or an unreliable source. This is a real confirmation from an animator who works with TOEI.
It is also important to note that SANDA confirms that he is not working on that animated production. This confirms that the project has already started to animate and he is not part of the animation.
This confirms that the continuation of Dragon Ball is already taking place and the animation process has begun, so it should be released next year. In addition, if they have started animating, a minitrailer of the anime or movie could be presented at this year's Jump Festa, as has happened in other years with the One Piece or Dragon Quest Dai movies last year.
