I think, no matter what it will be, if it's a roster of females as usual, a surprising male entry or a genderless-five-magic-stones-alike, we (as in the majority of the fandom) will probably be happy with it.
We have never seen original male ZUN-Art, so I'd like to see that as much as everyone else, but no matter what, if the story and the characters in it are interesting, nothing will take me away from it.
This time, I'm looking forward to new and unique gimmicks as I want to relive the surprise of a anchor suddenly getting embedded in my face! :3
I love the system of this new game so much and want to see how the later bosses will try to keep me away from them!
