This past weekend's Comic-Con 2013 return of FX's 'It's Always Sunny In Philadelphia' proved that the gang hasn't lost a step in 9 years, but the question inevitably remains over how long the cast will continue on with the acclaimed cult comedy. Previous assumptions had established that 'Always Sunny' season 10 (the second on FXX) might end up the last, but has series star Glenn Howerton finally confirmed it?

It certainly seems that way. Few indications of 'It's Always Sunny in Philadelphia's ultimate future were given out during the Hall H Comic-Con panel, but Howerton's most recent words with Rolling Stone leave very little doubt the Paddy's Pub gang will say goodbye after a tenth season, presumably airing in 2014. Asked about definitively quitting, Howerton said:

Yes. There’s a certain point where you wear out your welcome and we don’t want to do that. We want to leave them wanting more. We spend a lot of time trying to find new lines to cross. We’re not trying to offend people…but we’re looking to surprise them. I think we’re proud of what we’ve done so far, so it’s time to stop. I’m sure there are already a few people who are like ‘Jesus Christ is that show still on? Go away.

With the show moving to FXX this September, details are fast coming on ‘It’s Always Sunny in Philadelphia’ season 9, so far including guest appearances from actor Seann William Scott, singer Josh Groban and ‘Breaking Bad' star Aaron Paul. ‘Game of Thrones‘ showrunners David Benioff and Dan Weiss have written an episode, though the story of "Flowers for Charlie" won't have anything to do with the HBO series.

It remains to be seen if FX will have any comment about Howerton's words, but what say you? Should 'It's Always Sunny in Philadelphia' season 10 close out the series, or do the Paddy's Pub gang have life in them yet?
