"Which at this pace, could literally take another year or more" lol, what? There is no pace. There's a hiatus untill the new assets are done and then we'll get a big update followed by a normal schedule. No need for such exaggeration.
Silas art alone took months... you just have to do the maths.
The real problem is that people tend to forget very fast those vn that dont have an update every now and then. I think it would be better to use the old art for the moment and when the time comes it's only about replacing some of the code and nothing more (something that can be done in a "Art update" alone)
I don't know, that's my opinion.
