At this point, is Sony going to bet the farm on Killzone 2? It seems no matter what Sony does, US gamers just don't care.
They create one of the best FPS franchises in the last 5 years (R1, R2), create one of the most imaginative and original games in the last 5 years (LBP), and deliver a game that improves in every way one of the most groundbreaking games of all time (Tomb Raider, Uncharted). In 2008 you delivered the best software of all the big 3 (see metacritic). The 360 outsells you 2-1 in November (largely due to a sequel that actually does multiplayer WORSE than the first). Nintendo continues to kill it. Nobody gives a shit and your competitors are eating you alive.
So, what the fuck do you do at this point? You have the most expensive console that still loses money per unit. You refuse to drop the price. Your competitive position continues to be eroded.
Do you bet the hole fucking thing that gamers WILL care when they see Killzone 2?
