Killzone 2 demo ready to counter Halo 3 beta test? (UPDATE)

Apparently this rumor has been shot down, probably because the game has to exist to be shown!

"No, Killzone won't be at GDC at all," stated SCEA Manager, Ryan Bowling, in a conversation with IGN held yesterday afternoon. "The time for that game is coming and we'll have new information about it in the future, but not at GDC."
