I don't know if I should put this in the forum or as a blog, but this is more of my opinion... so I'm putting it here.
It feels like, no matter what the language at this point, 99% of vocals have anime-based characters.
I do like the entire idea of character vocals -- I think it makes the vocal a little bit more fun and interesting -- but it seems almost all the characters we're getting are anime-based.
I understand that Miku helped spread Vocaloid, Japanese vocals are the most sucessful, and what else, but I really wish we'd get more character non-anime vocals.
Don't get me wrong, as well:
Do I think anime is a good style? Yeah, definetly. I just wish that we'd get some more Western-styled characters. (maybe Ruby...?)
