What other types of Vocaloids would you like to see in the future?

Like if you could go up to a company and have them make what you would consider an ideal Vocaloid, what would you want. Gender, voice capabilities, language, pangkalahatang disensyo etc. anything you would like to see in future Vocaloids.

I'd like to see madami gender neutral/androgynous voices similar to VY1/VY2 and especially v flower. I'm also always interested in any new language or genre for singing. As far as box art goes it's always interesting to see when companies try to individualize their characters sa pamamagitan ng not doing anime art styles.
