Season 2 will start in late September or early October.
The Avengers: Earth's Mightiest Heroes Season 2 Information (Plot lines, new characters, etc):
According to Joshua Fine, Season Two is going to be the "Cosmic Season", where the Avengers deal with some big alien threats; we already know that the Kree-Skrull War is coming, from last Season.
Returning threats from Season One include:
• The Masters of Evil
Voice actor Wally Wingert "We're wrapping up the second season of Avengers from Marvel; I play Ant Man, Giant Man, soon to be Yellow Jacket."
Voice actress Erin Torpey says "I'm also playing The Invisible Woman in The Avengers and that's really cool."
Voice actor Peter Jessup has confirmed that he will be performing the voice of the Vision for AEMH.
Chris Yost has confirmed that Ms. Marvel will be joining the team, and the sneak footage we've seen of her shows her fighting the Kree, as well as Ronan the Accuser and (probably) Colonel Yon-Rogg.

seen 20 or so of the season 2 eps, so it's on it's way. S2 starts with a little tale called 'The Private War of Doctor Doom.' Chris Yost via twitter
Season 2 begins with the secret invasion comic storyline. The reason why Nick Fury has dissapeared since "Hail HYDRA" is because Nick Fury has assembled his own team to prevent it. Josh Fine via Youtube
