I would still be the project leader even if that happens. And I mentioned plenty of times that I start working on the Game 2020, which is still more than 8 months in the future, which should be over 32 more versions.
Also modded Minecraft for older Versions like 1.7.10 is starting to get serious Issues, Java 8 is for example no longer available through official means for Ubuntu anymore, so 2020 is probably a good time to reduce development on MC Mods and start with the Game, or at least start making the Game Launcher and infrastructure, because I want that to be done first before I do any actual Engine things.
