Joss Whedon is kinda busy right now. He just had a horror film (The Cabin in the Woods) released and is premiering (today in the US) THE tent pole movie of 2012, The Avengers. To go along with all his work, there is a bunch of media about him, the best of which is this GQ article. It goes into detail about his career. From Buffy (the movie) to script doctor to Buffy (the show) and Angel. Then two canceled Fox shows and a web success and a well-received (but mediocre box office) movie. This doesn’t exactly look like the profile of someone that would be handed the reins to The Avengers. But the article talks about this in detail. Go read it.
