I'm posting this as an archive because giving out demo CDs spiraled out of control in regards to trust. Release Video: https://www.youtube.com/watch?v=wyA_kDbQGgQ
Here is the email I have received from Bplats confirming the Nana Demos:
Email from Voctro about MAIKA:
I have contacted VOCALOID Store in regards to Mew. They have said yes, but have not answered on whether or not I can show the confirmation as of yet.
Crypton has not yet answered confirmation disclosure.. MEIKO V3 Power may be withdrawn at this point due to people not trusting me unless Crypton consents for the confirmation to be public.
I will post more confirmation as the companies consent to them being disclosed.
