What happens after the four Futurama movies?

I've bought the 3 that came out already, but what happens after the 4th one (Into the Wild Green Yonder). I've heard that they'll air the movies on tv in episodes. Will the show return on tv after that?

I think that if the four movies are successful, then Comedy Central will start showing new episodes...I really don't know though, it's sort of a grey area.
