Looks like we haven't seen the last of Extremis as Marvel Studios president and producer Kevin Feige lets is be known that we will see it again after Iron Man 3.
Feige participated in an Iron Man 3 Twitter chat answering fans' questions on a variety of topics.
One fan asked about seeing Extremis again, with Feige replying in the affirmative, "Yes."
A second fan asked what many movie goers were wondering about in the movie: What happened to S.H.I.E.L.D.,? As you think the covert organization led by Samuel L. Jackson's Nick Fury would have made its presence known especially considering the president's life was in danger.
Well, Feige says we'll get an answer to that.
"SHIELD was very busy, as will be revealed in future films," he teased.
