In a recent conversation with Joss Whedon at the SXSW festival it was revealed that neither the Skrulls or the Kree are the villain army in The Avengers. His reasoning for disclosing this information was to prevent the viewers from being disappointed.

“I will say only this: It is not the Kree or the Skrulls.”
“Those two aliens are Marvel mainstays and have enormous backstories,” Whedon explained. “They have a big life of their own that just could not be contained in a film where I already had seven movie stars.”
I have to respect Whedon’s decision on this. When making a film with so many strong leading roles there has to be ample time allocated for proper character development. Even though these characters have been established from their own respective films, the Avengers movie has to maintain a level of independence to captivate an audience that may not know of these characters and have not seen any of the films necessary to establish the characters. Introducing an alien race like the Skrulls or the Kree who have such a large backstory could make character development feel rushed and could hurt the fluidity of the plot. Sorry rumor mill, looks like it’s back to the drawing board…
