While some adult fans were hoping that Marvel's recent series Avengers Assemble will only last for a season, it seems the show has not only been renewed for a second season, but also a third.
It seems Marvel and disney Xd have seen the potential of the series, especially since, according to Daily Marvelite, Stephen Wacker is personally overseeing the show with promises of multi-episode story arcs, Classic Avengers stories adaptation and an expanding roster.
Expect to learn more details at SDCC.
