Mass Effect 2 Taking Shape?

Take a look at this teaser trailer, released last month for Mass Effect 2:

There have been few details released, but according to Amazon's product description page, which also lists the release date as Jan. 10, 2010:

"The second chapter in the Mass Effect trilogy takes you to the darkest reaches of space, where you must uncover the mystery behind the disappearance of humans across many worlds. Prepare yourself for a suicide mission to save mankind. Travel the galaxy to assemble a team of soldiers and combat specialists, and launch an all-out assault on the heart of enemy territory."

"Enemy territory" means fighting what's left of the Reapers or the Geth. Which means epic. Anyone else freakishly excited? The first installment in the series was probably my favorite game for Xbox 360. Now we just need some in-game footage.
