Although we already knew that Mass Effect was a trilogy and a sequel was on the way, EA and BioWare took its time to officially announce the game. A teaser trailer was released right after DICE, but specific details were still light.

"In this dark second chapter, Saren’s evil army of Geth soldiers has just been defeated, and humans, who are still struggling to make their mark on the galactic stage, are now faced with an even greater peril..."

“We’re going to surpass the extraordinary gaming experience we brought our fans in Mass Effect by delivering intensified combat and expanded weapon options as well as increased depth of planet exploration, all while delivering a powerful, emotionally engaging story,” said Dr. Ray Muzyka, BioWare's general manager and CEO. “Mass Effect 2 is shaping up to be an unforgettable RPG-shooter experience, taking players on a non-stop roller-coaster ride filled with stunning plot twists and no-holds-barred action."

Now, we finally have some concrete details on a release window and the platforms that the game will hit. Mass Effect 2 is currently scheduled for an early 2010 release on the Xbox 360 and PC.

Remember, keep those save games because your progress from Mass Effect will carry over in some way to Mass Effect 2 and hit the break to see that teaser trailer again.
