The creator of The Walking Dead, Robert Kirkman offered up this quote concerning the end of the series:
We have talked about an ending that we'd do if we ever got to that point, right before our joint suicide, but with the popularity of the comic, and now the show, I don't see an end anytime soon.
So, that's a "No" on the end of the comic, right? Good to know.
