I'm worried about this and feel like "vim" as actively maintained software probably also died today.
I don't really want to discus this in detail here as it's not the right location, but I think lots of people would be interested in continuing Vim, rather than having Vim being subsumed by Neovim. We'll have to see how things and the relationship between Vim and Neovim change and evolve in the coming weeks and months.
I have a weaker assumption - somebody will keep maintaining it, but active feature development is in question.
