Marvel has sent out a press release regarding the Avengers: Earth's Mightiest Heroes panel at SDCC tomorrow at 4pm. (See this post for more details.) After the weekend I hope to have lots of news to share with you! But in the meantime, feast your eyes on this new poster (above) that came with the press release! This is the best I've seen Iron Man in all the promo art so far. And the Hulk looks great too. I'm looking forward to this series!
Also, here is an image that was attached to the Marvel booth. This one features Hawkeye. Will he be a prominent member of the team? While not a founding member, Hawkeye is one of the longest-standing members of the Avengers. Plus, he would add a bit of comic relief. I found this via Avengers Site.
