Kaito and Meiko's V1 vocals were also retired, V1 isn't supported by Yamaha anymore.

To renew the license for Leon, Lola and Miriam to upgrade them to the newer engine will cost them more money then to make a new vocal for the new engine. Money prevents this from happening, as English vocals are lower profit then Japanese due to the size of their vocals (providers need to be recording in a studio longer) + length of development time. The average decent quality vocal for English can take approx a year and a half to do depending on how it goes. In contrast, a decent Japanese vocal can be coughed up in about 6 months - 1 year. :-/
