This is the first look at some concept art from Iron Man 3. You can make up your own mind whether this is a look at the extremis armour. Basically the extremis armour came about after Tony Stark injected his nervous system with a modified techno-organic virus to save his life. As a result it allowed him to store his armour in the hollow of his bones.
That said, in the concept art below, he might have just forgot a few pieces. Granted, when have we ever seen Stark without an entire suit?
