Are "The Avengers" Gonna Go Head-2-Head With The Skrulls & Kree In The Film?

It's been rumored that "The Avengers" 2012 film will feature The Skrulls and Kree as the films potential villains. No one knows really for sure who The Avengers will be going up against in the big screen feature film. Would be awesome to see them battle these guys.
