Of course one interesting consideration, should Netflix pick up the show - where do they start?
Given that a number of the writers of the show were actually responsible for the 'Season 3' graphic novel, and will presumably be contributing to the 'Season 4' one as well - how canon are those going to be treated? Would any new televised continuation pick up from where Season 2 left off, or where the 'Season 4' graphic novel finishes? I think common sense is going to demand that they pick up from Season 2, as many people are most likely unaware of the graphic novels anyway.
