As others have said, "soon" is a pretty big exaggeration. Hino works on this game alone, and in her spare time, for better or for worse.
She only said that Gardevoir is a planned pokemon to appear and they would be added later and given how much time it's been so far for everything, you're gonna be waiting quite a long time for the male MC to be added,(assuming she doesn't completely lose steam on this project and be sick of it before it get's done, let alone adding a male MC path for the whole game).
So unfortunately, all we can do as fans is just quitely cheer her on from the sidelines. Hino has definitely been open to suggestions, but she certainly isn't going to implement everything said,(for her sanity and for the game to not take 10 years to come out, at earliest).
