Finally found that one Zero-G facebook post that asked people what kind of library do people want to see next... It's here. Some suggestions from people the ZG Admin(?) passed on to producers; Miriam V4 (and other V1 and V2 loid updates), 'a new classical Vocaloid', a possible Spanish vb?, Avanna V5, and a 'Rock Chick' Vocaloid. I think there's even more suggestions. And this post is from August 2017 so I'm not sure how relevant would it be now but I find it interesting. Would be nice to hear what plans Zero-G has when it comes to their new Vocaloids or the franchise as a whole...
