No Extremus. it is cool and it would update the armor but no.I heard once that they where going to have tonys alcoholism as a factor in #3 and Hammer is back. maybe he joins with mandarin just to see tony suffer. I also think the head of the ten rings in #1 should become mandarin. he talked about gangus kaun and he well be looking for power and find one of the rings leading him to gather the others.
