If you travel in geek circles, the big news today was that Marvel aired the latest trailer for The Avengers during some... sporting event last night? Football? I don't keep up on these things.

Let's focus our attention on what really matters.

This trailer is the extended online edition which is somehow 30 seconds longer than what aired last night without telling us too much more about the movie.

I'd say Marvel is doing a pretty good job of whipping up a nerd frenzy. They're showing us just enough without giving away too much. With each additional release, they show a little more, but they don't go overboard. Clearly they know that the Hulk is their ace in the hole and they've done a good job obscuring him up to this point.

GeekTyrant did an excellent job of dissecting the trailer and grabbing stills - a few of which I'm going to share here. But you should really check out their article for more details.

Here's our best look at the Hulk so far.

And because you all know what a huge Iron Man geek I am, here are the two stills that got my heart racing.

Suiting up...

The Avengers, Iron Man, Tony Stark, Robert Downey Jr.

...and would you look at that? I see some additional back thrusters and shoulder-mounted weaponry in that still! Looks like Iron Man got an upgrade!

Yeah, I know, I'm hopeless.
