What other types of vocaloids would tu like to see in the future?

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

I'd like to see más gender neutral/androgynous voices similar to VY1/VY2 and especially v flower. I'm also always interested in any new language o 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 anime art styles.
