CFM have talked about adding further appends and more Kaito vocals have been made known via twitters even before the V3 release. Basically "watch this space" I guess is all we can say.

I imagine the current vocals were limited to what they were because they added the english bank with the package, which would have taken up enough space for 2 or 3 more japanese vocals. :-/
