Killer apps are the kind that deliver an experience you cannot get elsewhere, not yet another brown-and-grey FPS in a generation where that seems to be the only genre in existence.

Most people who like games own a current console by now.
The PS2 alledgedly sold (or at least shipped) something like 140 million systems. The PS3 and 360 combined are currently about equal to the Wii's userbase which is still way short of 140 million. All current gen consoles combined don't reach 140M. Even if every PS2 owner bought at most one current gen system with zero overlap (not gonna happen) that's still quite a few million unserved customers and that's before we consider that the Wii reached people who didn't even have a PS2.
For Sony to grow it's console base, the biggest market is 360 owners.
No, the biggest market is PS2 owners, the second biggest is Wii owners. Well, if we ignore the DS. Know what the DS and PS2 have in common? A massively varied game library. The Wii has a very broad but not particularly deep library (i.e. many genres with at least one game but each genre only with a few games) though that'll probably get fixed over time. The PS3 already has FPSes in large numbers, the only console that will experience any major growth from major FPS releases is the Wii.
So, the PS3 has had a few excellent exclusives that didn't really push the system so much as make people who already owned the system happy about their purchase. This is nice but an exclusive defines the console and should help sell it. So, will Killzone 2 make you purchase another console, are you waiting for God of War III, or do you see your console like a girlfriend and a second console would be cheating on the first one.
KZ2 will definitely fall into the "make existing owners a bit happier" category. It just fails to stand out, looking generic in every way. Yeah, okay, it may be a bit prettier than other games but last I checked the "pretty" systems are getting blown out of the water by the not so pretty one. It's a bit more padding on a category on the system that's already overserved by the whole damn generation. If the PS3 was utterly starved in the FPS genre, sure, there might be sales but it already has enough that those who want FPSes have one.
Me, I'm not considering the PS3 at all. The reason is simple: 400€. I paid that much for my Wii and 360 combined (200€ each, the Wii was cheaper because of cost splitting). Well, okay, the other reason is that to me the 360 and PS3 are practically identical with most of the big games being on both consoles and the PC and I already have enough trouble finding anything I like on the 360 (that's not drastically cheaper on the PC, the price differences are ludicrous) with this whole grey-on-brown-shooter fad going on.
