According to Wacker, we will see more Avengers (an expanding roster) and more multi-episode stories (unlike the first season which only had mostly single stories episodes). Wacker even hint in one of his replies, that the show will offer some classic comics adaptation, a concept highly praised when utilized in the previous avengers show, Avengers: Earth's Mightiest Heroes.
Oh my god. Can't they just bring back EMH? Either way, the whole classic comics adaptation and an expanding roster might be good signs of this show improving.
