The series were pretty popular, and the anime only covered half of the manga, so it could be that they'll do a second season. Also, the end served as a pretty good start for a sequel, so it's possible. But we can't presume that they'll make a new season until Manglobe has confirmed it. Best case scenario, a second season will come in December or so...
