Bootleg 'Avengers: Age of Ultron' teaser from Comic-Con

Yep, not much here in this bootleg teaser for The Avengers: Age of Ultron.
However IMDB does have an updated synopsis:

As the US Government create a force, known as Ultron, The Avengers are told they are not needed any longer. But when Ultron turns against Humanity, it's time for The Avengers to assemble yet again for their most dangerous challenge ever.

Odd, so according to that, the Government is going to be who builds Ultron? Interesting.
