Personally, I'm hoping Iron Fist gets himself a nice anti air move similar to Chun Li's triple kick but with some invincibility to it, or some kind of seismo like move that puts up an energy barrier like a Seismo had mated with Jam Session.
Or he just comes out and DECKS YOU. Invincible Iron Fist standing there as a counter. You approach while he is out there and he punches you with the fury of an angry God! Literally.
God I can't wait for him to debut. I've waited 15 years for him to be in a good fighting game and he's going into one of the best. More importantly he is going into my personal favorite! Team "Ive waited 15 years to put Iron Fist on point" will ascend to a legendary moment in my gaming life as a dream come true! I will play him day one on my Ponystick and I will fly off into the heavens upon a rainbow of Friendship and Manliness unlike anything ever thought possible!
MANLY PICTURE TIME!!!!!
EDIT: I haven't slept much this past week ...
