Earlier tonight, the viral ad campaign that has been going on for Iron Man 2 for the past week culminated in a ticking timer on www.starksecretconfessionrevealed.com. And what was waiting on the other side of the clock? The new trailer for Iron Man 2.

The trailer’s now up at Apple in full HD glory, but you can also check it out below the jump. The trailer teases a lot of what we can expect from the new film — namely, plenty of high tech battlin’. Mickey Rourke’s Whiplash makes a significant and splashy debut, while Don Cheadle’s War Machine also squeezes in his hero shot. All in all, a fairly epic trailer. But it’s no fun listening to me talk about it, hit the jump to see it for yourself!

Looks like Tony Stark’s going to have to face some demons by coming to terms with the fact that after years of running a weapons manufacturer, there are going to be a lot of people whose lives have been ruined by the weapons his company once peddled. And as if that wasn’t enough, he’s got the government breathing down his neck for his weapons technology, a smokin’ new assistant in Scarlett Johansson, and battle suits chasing him around. I can’t wait to see how it all turns out.

Iron Man 2 is an agonizing 142 days from release — it comes out on May 7, 2010.
