You guys are both wrong
"TIM KRING - "Do you know where you\'re going?" and "Do you know the ending?" are two very different questions. I know where we\'re going in great detail for the first half of one season. We have a real sense of where we want these stories to be by the end of season one. We have a broad sense of where we\'ll go in season two. I have some ideas about farther down the road, but I\'m pretty superstitious about that.
As to needing an ending — Unlike LOST, we have not set up a central dilemma that has to be solved, therefore concluding a larger quest. There is no island to get off of on HEROES. Instead, it\'s a show about characters dealing with extraordinary things happening to them. That is the central premise. So my sense is that if one can assume that dealing with their extraordinary abilities is something that these characters will always face, then their stories can bend and morph and evolve forever."
I think you are confused by the fact that they have stated that they are going to try to wrap up this Story Line. But the show is definitely multi season bound
