Just so people know...
I met Rob D at London Expo 2013 and spent a bit of time with him talking about animation. I asked him about Joe Zombie 7 and as far as he knows it's still just a storyboard and he might finish the series - might - because of how much he's changed with animation (especially with Cyanide and Happiness + Explosm Entertainment).
All in all, we can only hope for the next episode.
Apart from that, always been watching these and I'll always remember them!
