Interestingly...the teaser for Attack of the Clones ended up in front of Monsters, Inc.

That was the teaser for the teaser (the "breathing" trailer). The first full trailer was in front of Harry Potter.

I doubt we'll see anything until next May at the earliest. I wouldn't be surprised if Disney attaches it to Tomorrowland just as a little added incentive. Avengers 2 is guaranteed to make bank and doesn't need the help. We'll probably see it officially online earlier that week, though. I feel like studios holding off on uploading trailers until the Monday after is becoming a rare occurrence.
