That Avengers: Age of Ultron trailer?

The one that was going to air during or after next week's Agents of S.H.I.E.L.D.?

It leaked.

At least I assume it's that one. It might be a completely different one. But who cares? It's an Avengers: Age of Ultron trailer. (I expect in the UK it'll have to be called Avengers Assemble: Age of Ultron... *g*)

I'll be in my happy Natasha Romanoff place. Squeeing and flailing like mad.

ETA: And now Marvel's uploaded it to Youtube, with embeddable links and everything...
