According to Latinreview a new villain is being introduced for the avengers movie. That villain is THANOS. So with loki and the hulk as other possibly villain could we see loki and thanos working together only time will tell. Also to debunked this rumor the skrulls won't appear until a sequel.

For some people that don't know who thanos is here is his background.

Thanos' first appearance debuted in the Bronze Age of comic books, and the character has featured in over three decades of Marvel continuity and a self-titled series. The character's name is a derivation of Thanatos, the personification of death and mortality in Greek mythology. One of his zaidi prominent storylines to date—the Infinity Gauntlet series—portrayed him as a mad cosmic tyrant bent on slaying half of all sentiences existing then in Marvel's multiverse in order to appease the Marvel Universe’s actual (and zaidi powerful) embodied personification of Death in an attempt to win its love.
So what do wewe think about thanos being the villain the avengers movie.
