Voicebanks you're surprised haven't been announced for the Vocaloid engine at this point.

For me, I'm surprised Zundamon still hasn't gotten a Vocaloid voicebank. When I saw they funded Adachi Rei getting one, I thought that naturally, at some point, Zundamon would be added to Vocaloid since she's on EVERYTHING you can think of except the big ones (Synth V and Vocaloid.)

Other ones I'm surprised haven't been brought back to Vocaloid/gotten updates.

With all the advertising Gumi has with Gakupo, you'd think they'd bring him back at some point. Though, it feels unlikely.

Fukase was pretty popular and even bundled with V5 for quite awhile. The fact he hasn't gotten a V6 baffles me. And, I guess same with Flower, but she's on CEVIO...

Rana. I always wish they'd bring her back.

Piko... rest in peace, Piko.

Surprisingly, Meika and Mikoto Hime were never given a v6 bank, though I doubt they ever would.

Some voicebanks from v3 that we haven't seen since (but had updates on other engines):

Aoki Lapis
Lily (who is/was extremely popular in Japan.)
MAYU

Voiceroid characters that have no voicebank to sing:

Minase Kou (though i don't think he'll ever get one)

That's all I can think of.

I'm surprised that there haven't been any Spanish voices since MAIKA, and she was on V3. I understand that they'd likely have to add Spanish as an XLS option and that would take work, but right now if you want Spanish synths your options are MAIKA (stuck in Vocaloid 3), SynthV (only has two native Spanish singers with one of them being American accented and the other focused on Opera, XLS is available but apparently spotty), or UTAU (questionable quality at best).

I'm a little bewildered as well that Gakupo hasn't been updated, but it might be because of his VP.

The fact that there are barely any V6 appends is quite surprising to me, especially since V6 does have XSY capabilities. The only appends I can think of are Gumi V6 Solid (sold separately) and Miku V6 Soft. There might be some other way to influence tone with V6, but I know next to nothing about it due to its lack of interesting voicebanks.

Speaking of interesting voicebanks, why haven't there been any updates to any of the genre-specific Vocaloids? I know that flower's taken by CeVIO, but what about Sachiko? I feel like she would work much better with the V6 AI engine than she did with concatenative synthesis. And I know that Zero-G's out of the Vocaloid business, but I could see Yamaha purchasing the rights to Prima and Tonio and updating them, especially with the release of GALENAIA for SynthV. Lord knows it would do wonders to their quality. I love them, but goodness they are full of issues.

i've always been a little sad maika never got an update in general, because though voctro got absorbed by voicemod and has shifted focus onto... i think mainly other ai things, they still had close ties to yamaha so i feel like pulling a 'eleanor forte gets adopted by ahs' never seemed totally out of the question, plus i generally feel like they'd be able to hunt down the vp if they wanted to

i know it's more difficult than that, especially because i think yamaha just found it difficult to market spanish vocaloids even though it does have a big fanbase of its own. but thanks to v6 maika could just be marketed as, like, THE multilingual diva as she should be!
:(

Im honestly shocked that they just stopped with the actual VY1 updates tbh she was always one of the highest quality vbs for any engine she was on but they just disappeared my queen
