The long-awaited third installment of the Iron Man franchise--okay, it has not been that long since Iron Man 2, especially with Thor, Captain America, and The Avengers to keep moviegoers company.  But, I digress.  The new teaser trailer for Iron Man 3 is here.  It is nice to welcome back Tony Stark and Pepper Potts, and who could the new baddie be?  Watch the trailer and see.
