I was planning on making it 3rd Edition, because I haven't actually learned 4th Edition yet (I'm old fashioned- I like to learn character creation first, and then the combat system with a 'back to the shack' kind of scenario, and then actually jump in to getting double crossed.)
If you want to play, feel free to jump in. If you want to wait for a 4th Edition thread, give me a while to learn the system, and I'll start in on it. (Ruski would probably be the better GM for it, though)
