If I'm not wrong, I think I remember something similar happening with Ruby and V4. She was being worked on the V3 engine but then was being worked on V4 when its release was close. Someone from PFX accidentally announced it on an email. So I don't think it's impossible to be working on an Vocaloid for the engine, even if it's not officially announced.
