Well the Internet Co Artist Series has always been there since Gackpo was released but it kinda stoped when Ryuto, CUL, Galaco and Kokone.

As for miki-chan, I assume AH-Software had plans for an "Artist Edition" series, but it came to fruition and miki ended up being their only Vocaloid to voiced by someone famous. Unless you count Zunko, but she's more similar to Yukari.
