Portal 2 trailer bounces out

Say 'welcome back' to GLaDOS

The E3 trailer for Valve's Portal 2 is here - and GLaDOS is back in a starring role.

The video first aired at Sony's E3 conference earlier today in Los Angeles.

One-time PS3 hater Gabe Newell took the stage to declare the Sony platform was getting the "best console version" of the game.

T'was a big shock.
