Super excited about this project! I've been a Vim user for a while but I like the convenience of Sublime thus my Vim skills have to limited to Vintage mode in Sublime.
WebStorm; didn't mind learning some of the settings but find that there's just too much flicker and slowness.
MacVim; Most recently I spent a bunch of time playing with different package managers (Vundle and Neobundle) and getting a basic setup going and realized I don't have to do all this troubleshooting in Sublime.
Then I stumbled across this project via http://thechangelog.com/
It makes me want to learn Python and the Sublime API!
Thanks Ryan! Really want to see Actual Vim prosper and I hope I can make time to contribute.
