Killzone wont feature pre-game installations

Run out of hard drive space on your PS3? Like Killzone2 but scared that the game will feature gigantic pre-installation files that will consume your PS3's remaining hard drive space altogether? Then rest assured my friend, for at PlayStation Official Forums, Seb Downie, Guerilla's testing manager reported that the game will NOT feature installation-optional or otherwise! So, Rest.In.Peace until then!
