A video appears, but it's only for select members of the video game press.

killzone 2 - Killzone kind of a no show at GDCIt didn't look like the original E3 trailer

Although Sony had mentioned that a new Killzone PS3 trailer would not be present at this year's GDC, the past week has seen a steady flow of rumours saying otherwise.

Unfortunately, Killzone was (once again) nowhere to be seen, although attentive audience members of Harrison's keynote speech were briefly teased near the end of his presentation when he scrolled through a PS3 menu right passed what appeared to be a video file titled 'GDC Killzone'. A few gasps in the audience could be heard, but sadly, Harrison never hit play.

But he did hit play during a behind closed doors demonstration of Sony's new PlayStation Edge suite of development tools. While strictly labelled as a tech demo and not an indication of the final game, it is at least proof that the game exists in some form. According to Harrison we'll see more of Killzone for PlayStation 3 at E3 in July.
