The Walking Dead executive producer Robert Kirkman recently appeared on Entertainment Weekly's Sirius radio program, where he revealed new details about Season 5 of the hit AMC series.

As you may recall, Season 4 ended with Rick (Andrew Lincoln) and his group of survivors getting locked inside a train car at Terminus. Robert Kirkman revealed that the group will definitely make it out of that train car, while teasing (possibly joking) that a major cast member will die.

"They definitely get out of that train car. They do not spend the entirety of Season 5 in that train car. It is through ingenuity and creativity and somewhat savageness that they are able to make their way out of that train car. They are definitely not in that train car for multiple seasons, so we don't have to worry about that. There will be resolution. There's a lot going on with Terminus. In our premiere episode of Season 5, we're going to give a ton of answers of who the people of Terminus are, what they're doing, why they're doing it, what's going on with them. And by the end of that episode you're going to have a much better understanding of what's going on with them and why they're so important to the show. I think that's pretty much all I can say. Oh, and Daryl dies."

Do you think a fan-favorite character like Daryl (Norman Reedus) should be killed off in Season 5? Robert Kirkman was likely joking when he said that Daryl will die, but, of course, anything is possible in the zombie apocalypse.

When asked how long he envisioned the show running, Robert Kirkman revealed that, since he is still writing the comics, it's possible the show could run as long as 15 seasons.

"It's a tough one, just because I'm still doing the comic, and we really love what we're doing and plan on doing it for many, many years. And right now the issues that we are doing as we speak is material that could be adapted into a season 10, 11, or 12 depending on how we adapt things. And we're not stopping. So five years for now we'll be doing comic books that could be for season 15. Now, it's unrealistic to think a show can go for that long, but if the show remains successful, the potential is there for that. It's kind of a strange endeavor, because the show is doing so well, and the source material is not ending anytime soon. All that said, I'm just hoping and praying we make it to season 7."

David Alpert, another executive producer on The Walking Dead, revealed earlier this month that the show is currently planned out through Season 12.
