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, no geral, global design etc. anything you would like to see in future Vocaloids.

I'd like to see mais 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 por not doing animê art styles.
