Killzone 2 Demo To Kill Halo 3 Beta Buzz?

Kotaku is reporting that a playable demo of the second installment in Sony's Halo-killer-wannabe Killzone franchise will be available before Bungie hits Xbox Live with its extensive Halo 3 Multiplayer Public Beta. Kotaku heard it from über Halo fan Luke Smith at 1UP, and I heard it from P_40E in #hbo.
