They didn't bother updating their vocals in V3... IT just they wanted to keep the characters alive in V4. Technically Internet co updated all their vocals from V2 to V3. ITs not always possible to do.

The "Yamaha" vocals are also not a united group, so we shouldn't think they all came from Yamaha and are one company. Yamaha vocals are 3rd parties who went through Yamaha.

Also, the difference between V3 and V4 as voicebanks goes is this; XSY and GWL. Not much has changed apart from this except the way a vocaloid is recorded, of which Tone Rion and Nemu should the differences between old and new. There is no need to update every vocal to V4.

Technically also... AllCFM vocals are updated to V4. Meiko and Kaito aren't 100% CFM's, they were Yamaha's. So in truth, they don't really count. :-/
