It seems we're back to square 1 with the fanart at DA, with it all pretty much being centered around Miku and co. The hype of the new vocaloids for V3, with the exception of Ia, seems to have died down. The only difference between now and pre-V3 beyond Ia, is that Gumi and Gakupo are finally getting more distinction.
There was an odd occasion Oliver fanart when I looked today, but thats not been the common trend.
Overall things are proving disappointing, since this is something I hoped would square out someday. I tend to think places like DA often provide a glimpse into the psyche of the general fandom and what it likes or thinks is most popular. :-/
