Half-Life 2 for PS3 Delayed
In an IGN preview it has been confirmed that the PS3 version of Half-Life 2: Orange Box will arrive weeks later after the PC and Xbox 360 versions are released on October 10. No specific reason was provided for the delay.
Their preview of the game has them describing a new section of the game involving the ever-lovable Alyx and a combine advisor. They have a video of that segment, which I have embedded below. The rest of their preview talks about the Xbox 360 version of the game, as well as the PS3 version of Portal.
