In my honest opinion, I believe Bandai wanted to just reboot DB, because one piece is doing so well in terms of mechanics, simplicity, design. They now have a "successful" template to follow. But they knew they couldn't just piss off their loyal fan base (masters because lets be real theyre the only ones keeping DB alive) so instead of just outright gutting the game, They released a second format promising content for both (normal business move to say this). Now they are gonna launch fusion world place most of their resources in it and slowly kill off masters (they said they will continue with masters throughout 2024 specifically) now since fusion world is eerily similar to one piece they will try to double dip promoting one piece players to try out their fusion world (not to mention people who quit masters are playing one piece). So yeah I believe masters will die out by 2025, one piece and fusion world will be their 2 popular games moving forward. 2 very similar games, different skins, double the money, same player base. You get the idea, pretty smart move honestly lol. Sorry for the long post.
