Check out THE AVENGERS: AGE OF ULTRON Teaser

Thanks to the JARVIS iOS app and the Iron Man 3 Blu-ray, we now have access to the teaser, or announcement trailer that was shown at SDCC announcing the Avengers sequel; Age of Ultron.  Check out the video below.

To me, while you hear voices of the other Avengers, the only imagery comes from Iron Man, which to me strongly suggests what most people are assuming, that JARVIS will in some way be connected to the creation of Ultron.
