Edit: Official Avengers: Age of Ultron Trailer!

Oh how we've missed some quality comic book action.
It has been nearly three months since we were last blessed with Marvels Guardians of The Galaxy and how awesome was that?!
In true awesome style the trailer to the latest in the continually developing universe Avengers: Age of Ultron has leaked a few days ahead of the intended premiere of the trailer.

Hurry up and watch this because it will most likely be gone by the time you've finished reading this sentence.
I'M TRYING TO KEEP UP

All links were pulled in the space of 45 minutes.  Well played Marvel, well played.

QUICK HURRY!!!
ANOTHER!

UPDATE

Disney/Marvel fell to the pressure and officially released it. 

ENJOY!
