^ You have a point, but you can't really use Gumi, Lily, Miku, and Gachapoid as examples. AHS has nothing to do with them; they belong to Internet Co. and Crypton.

AHS has never updated old vocals before just now, so we can't say anything about them using old or new recordings. (I have no idea if Yukari's Jun bank is new or not.)
