I doubt anythings changed since the last time there was discussion over it. As far as I know Nin Nin is still working on a conversion of one of the japanese VN games, a couple were started like the Dragon ball Z game but it's progress stalled.
I think the biggest problem is just it's a little time cosuming to work out the structure of a Virtual novel. I still have hope to create one as it's really a very open system, I just need to take the time to understand it fully, which I havent had much free time and a few other unrelated progects. Which I beleive both Nin Nin and Virtual Leech and both offered help to anyone that needs help.
