1st Place have announced that IA V6 has been in the works, and will be properly revealed on 15th December!
I've never been a big fan of IA's quality on CeVIO, and it's long bothered me that the only English version of her available was stuck on CeVIO, even though its quality at the time was a bit worse and more tinny than Vocaloid. I'm so glad she's being upgraded to V6 (even though people love to trash it, I'm mainly excited to hear her English cross-lang).
