Square Enix announced in the latest issue of V-Jump magazine that Dragon Quest Monsters: Joker 3 Professional will be the end of the Dragon Quest Monsters: Joker series. [Thanks, Ruliweb, via Game Jouhou.]
The magazine calls it the “Joker series’ grand finale!” where you’ll witness the “climax of Joker,” and they call it the “Joker series’ latest and final title.”
As far as game content goes, it’s been revealed that the ride system has been upgraded, and will allow you to mount giant monsters. There will also be new areas that we’ve yet to see, about 700 monsters in the upcoming title, along with plenty of new skills and characteristics.
Dragon Quest Monsters: Joker 3 Professional releases in Japan on February 9, 2017 for Nintendo 3DS.
