Extended Avengers 2 Trailer

This is sick! 

So it looks like the Avengers have fallen on hard times.  There is in fighting and people look like they are in trouble.

Tony Stark is the man, what is Thor doing choking him?  Why are Iron Man and the Hulk fighting?  Scarlett Johanson's but won't quit either.  Snow, Fire, explosions, chicks, I'm in!
