From what I've seen, all V3s can run in V4, even if they are limited trials without a key. Hell, I'm sure if they wanted to those who earned Galaco's prize vb or got Ring's βvb could install them on a new computer which has V4 and run them for a couple weeks untill they expire. I think that V4 has it built in so it can read V3 (and imported V2) voicebanks with ease. In fact, with this feature I don't really see a need for many V3s to be updated. Only those who I feel that GWL could be usefull (like v flower) or are hare to come by and a V4 release could make them easier to access (like Rana. For example, the updates for both Zunko and Rion I feel weren't really necessary however, if Lily or MEIKO were updated the GWL would be beneficial and complement their voices. Also, if they re-recorded Lily I think it may add some extra clarity that her V3 lacks. The only reason that I found Yukari and GUMI's V4 updates to be beneficial was because they got some extra, brand new voicebanks. As for Miku, although the GWL did work for her (and there's that E.V.E.C. thing), I feel that her V4 update was mainly a cash gab and the only VB of hers that actually needed the update was her English which from what I heard is rather lacking.

I wasn't expecting this post to be nearly as long as it was
