Update on Iron Man 4: It's Not Happening

Yesterday, Robert Downey Jr took to Ellen to promote his new film, and ended up telling everyone about Iron Man 4. Turns out, he was wrong, there's no Iron Man 4 coming.

According to Downey Jr, "There's a plan" in the works for his continued involvement with Marvel, but first, he has to stop Ultron and Thanos in Avengers 2 and 3.
