Hey Everyone here is a new Mass Effect 2 Cinematic Trailer that came out last night ! 
 http://www.youtube.com/watch?v=gPxGl46P4FM  
This is only around half of the trailer. The full thing will come out Dec. 22nd on XBL. 
**Spoilers**
In this video there are a couple things you might have missed:
1. The Biotic that breaks out of the prison is believed to be Subject Zero. 
2. When I was reading through the mass effect 2 forums on there site and someone posted this -- http://img686.imageshack.us/img686/664/tali.jpg
In the first image you will see the full computer screen. Look at the image of Shepard (N7) then look at the image above his and you will see a familiar friend (the number on his ID photo is C28)!!!
This indicates that he is going to be in the squad but it is only speculation.
 

I'm kindof hoping it's not Morin and it's instead Captain Kirahhe.
 
I AM SICK AND TIRED OF THESE MFING GETH, ON THIS MFING LINE!

why does the short bit of scene right after the word "purgatory" remind me of the pokemon movie where mewtwo was created?

That's some mighty purdy cg right der I tell ya wat.

Looking good, i plan on definitely picking up the game.

Prrruddddddy cinematics.
 
I wonder when we can play a game with that good looking graphics...

Thanks for the link.  
  
That's probably what the PC version is going to look like when I run it on max ^ ^. 

Here's the latest trailer for the Sentinel class, too. Sentinel's get their own tech armor which blows up after being depleted.
 

Who is above Shepard on the console? I can't make it out clearly. Who is C28?

Man that looks f'ing suh-weet. Give. Me. Now!

I was under the impression that we already knew Garrus was a squadmate?
