Shinichi Kameoka, who is the president of Brownies and whose past accolades have included Seiken Densetsu, Mother 3, and the recently released Egglia, has confirmed via Source Gaming that the company is working on a new project for the Nintendo Switch. The game will be revealed by the company this summer. Japanese Nintendo says it is not an actual RPG but will be “something kind of like Egglia.” The game will contain some elements of both breeding and training.

I like this kind of game. Very interesting, Can’t wait. Just like the game How to train your dragon.
So no to a proper remake or new adventure in the Mana series?
No thanks brah, keep your minigames
I still want the Mana collection that Japan got for the Switch.
