The Hong Kong Publishing Fair has an interesting promo image for The Super Hero Squad and the upcoming Earth's Mightiest Heroes! The Avengers animated show. The image as seen below, has pretty much the same line-up with an exception or two.
Could this be Marvel's way to go ahead and present the Avengers as Captain America, Iron Man, Thor, Hulk, Wasp, and a couple of extra heroes as the "real" Avengers in anticipation of the movie?
Looks to me that they are trying pretty hard! You be the judge!
