Killzone 2 demo exclusive to GameStop, public demo after game release

PS3 Fanboy writes: "The only way you'll be able to play Killzone 2 before the game's release will be through GameStop's exclusive pre-order campaign. No other demo for Killzone 2 will be released before the game's street date. Those that don't want to pre-order from GameStop will have to wait until after the game's release, as we've discovered from SCEA. "The demo will be available on the PSN after the game ships but only through GameStop until then.""
