Piko wasn't successful at all.

Sony also seems to have more or less stopped caring about him the moment he was released (not to mention they pretty much ruined any chance he had of being popular before then).

Yanhe, meanwhile, was only the second Chinese VOCALOID and thus Chinese producers didn't have a wide variety of voices to choose from. There were plenty of Japanese VOCALOIDs before Piko.
