I don't really see any problems here, they haven't made any promises either to release anything either before they are up to speed with where they want to be, just looking at their Github repo shows that there's a lot of activity going on. I'm really looking forward to seeing where they are going. In eight months things may have changed drastically, who knows, but I think that NeoVIM is going to be great. Besides, this is a bit like complaining about vim being a fork of vi, it's how things goes with open source software.
