Long story short, one thing that lingers on is what to make out of these girls. We've got 1 page with the word "Vocaloid" on it in the source and pretty much nothing else on them.
They are a mixed bag of ifs and ums, all of which have left us with the big uncertainty of WHAT to do with them. They stick out also for the upcoming September stuff as they are in the misty part of things. The problem is they were not flat-out stated as vocaloids everywhere else they appeared and things have just gotten really confusing.
So... Should we decide on them indefinitely?
I've always been fine with calling them vocaloids, its just we had only 1 source, a source that was obscure and hidden. You had to look at the page source to find it. But this leaves a lot of unanswered questions too in the process of how to handle them. At this stage there are more and more "private" vocals being created which means we've got to a stage where if they are what you'd call that, there is more understanding about what they could be. :-/
Edit: Also to highlight that even the Japanese fandom was clueless on their classification, the nico-nico-douga-wiki-thing also pretty much says "we don't know either".

Edit: Also thought it was time a picture of the keyword "Vocaloid" being highlighted on the source for their website.
