The chinese Vocaloid side has shown the most promise.

Currently its (from strongest to weakest):

Japanese -> English -> Chinese -> Spanish -> Korean

I've had nothing against SeeU personally, I think the vocal was overrated and she only got attention in the overseas fandom for the cute avatar, proving how shallow this fandom is. I gave up with SBS after the whole "multilingual, can do English!" vocal claim about her Korean vocal. at least with Maika and Sonika they said "will not sound like a native and require manipulation". :-/
