yeah, i know, its a whole year in advance...but does anyone know who the bad guy is? in the comics and the shows, they, at times had the hulk as the enemy. but then again, they also had hulk as the good guy too. when he was bad, it was very hard for anyone to beat him. but when he was good, no one bothered getting in his way... also, the cast shows that loki would be back in the avengers, perhaps he's playing the villain, or maybe a sidekick to a villain. i never saw loki too powerful to be a problem for any of the avengers. and even if loki does summon the ice giants, thor can easily destroy em (not sure what captain america can do), and same goes for hulk and iron man. Thor (the movie) did say that their universe is divided into 9 sections. asgard being one of them, the ice titan world being the second one, and earth being a third. could the main villain be from the remaining 6 worlds?
