Surprised no one posted an image of her new design (she wasn't featured in the announcement):

Probably because they would need to translate all the dialogue is featured in the trailer, the menu and things like that. Nintendo have announced some titles in their japanese direct that they weren't featured in the west direct, but later they were featured, like the last Dillon game. And, if not, people can push other companies to localize them like Culdcept.
Being a heavy-text game and not done by Nintendo themselves probably means it won't have an international release, and it will be localized some time after. The big problems of this game are, probably, they won't translate to other languages like spanish, italian and maybe french and german and a lack of a physical edition.
