Update: Apparently this is a legit promo poster spotted at Licensing International Expo in Las Vegas.
Things to look for: Captain America (Chris Evans) modern outfit, Mark Ruffalo’s HULK and Hawkeye (Jeremy Renner) is finally suited up.
Update II: Yes the IRON MAN suit got a revision; it’s got silver parts on the back & chest plates.
High res cleaner version of the poster can be found here
Look at what I found.
