Just found out about this news~ And it seems it isn't reported on any English websites yet~
On June 8th, YAMAHA hosted a Nico Nico Douga live stream and released news about the upcoming successor of the Vocaloid system - Vocaloid 3 (called Vocaloid 3 editor)
As I read through, it looks like they are really shooting for making Vocaloid a multi-language and international culture trend. I will do my best to give a summary of the event information.
