Well, you should consider a couple of facts, the first being that huge games require a lot of development time specially if the dev team is small (afaik Viraginis is on her own right now), take as an example Monster Girl Dreams which is still in alpha after more than 6.5 years:

And you gotta keep in mind that if SV is strongly inspired by Bully, it's gonna be quite a while longer until final release since the dev isn't backed by a full company of developers (this isn't a Rockstar project, you know).
And last one, is that the dev posted a few updates on development on Patreon on all this time (and some of them made it to DeviantArt too), and though they were released at a slow pace, the fact that she took her time to post just teasers on DA makes me think she's not just milking (milkers tend to not give a damn about people outside Patreon, and even if she was looking to advertise her Patreon, she would have posted her link in more than just a handful of her deviations' descriptions).
I'm not saying, "support her now". Because I also understand your POV and also consider wise to wait at least until the playable demo is out, next thursday. But I don't think the game should be dismissed for not being over after 3 years, and even more if you remembered the game just today and didn't follow the updates through time.
