Need help identifying a film.

When Tess and I went to see Transformers (a rather rubbish film I hasten to add) there was a trailer at the beginning which looked rather interesting. Probably an equally rubbish film, but it was trying to be all mysterious by not telling me what it’s called, just that it’ll be out next year. So, here’s what i saw, anyone know what film it is?

A whole load of 20 something nobs in New York are at a party and being filmed ‘Blair Witch’ style with a dodgy shaky-cam and drunken idiots leering at me. I think it was a party ‘cos some bloke was going away somewhere, I’m not too sure. See, it still looked rather shit at this point and I wasn’t paying much attention. Then it gets interesting.
Shaky-cam gets even shakier as there’s a booming noise, and everyone starts running out of this appartment onto the roof, or the street, too see what’s going on. In the middle of the city is a huge and growing fireball with big burning bits of debris flying out of the explosion. The bits of debris start flying towards the shakey-cam and everyone ducks and whimpers etc. Then the scorched head of the statue of liberty drops into the street.

Name that film?
