I don't agree, none of those are big except Gran Turismo.  People are picking up Playstation because of brand, and because most games are available (mostly multi-plat) plus blu-ray.  If Sony had to depend on those games alone they would be screwed big time.  If PS3 was put in a GC situation it would be dead in the water. 

Playstation was successful last 2 gens because of mistakes of other companies and 3rd party exclusives.  They never depended on first party.

^^Agree 110% with CGI on this one. Sony did not dominate the last 2 generations based on "mistakes by other companies". Seriously? They don't depend on first party? I would agree that they don't focus their entire business model on 1st party titles, but that is one of their model foundations I can promise you.

Playstation 1 was a success largely because of the mistakes of the competitors, if Sega and Nintendo would have done the right thing Sony wouldn't have had a chance.  Most people will agree with that, the mistakes were huge and numerous.  That's not even the point of this, i'd prefer not going down this road.

you're not really disputing my main point, my point is that if Sony takes care of their franchises they can make more money from each game, and have must buy games that generate hype for the system.  Right now you can only say that about Gran Turismo, and the other games are quite small in comparison.  Look at Nintendo, they can release Mario Party at any time they want, and it's gonna outsell all those games on that list except Gran Turismo (probably double or triple most of them sales honestly).  Mario Party is gonna cost a small fraction of the cost of killzone 3 and outsell it.  Nintendo finally did the right thing this gen and took care of mario party, something they didn't do in the n64 and gamecube generations.  Why do we sit here and say "but that's Nintendo, come on."  Sony can do it to, but instead they kill most of their franchises over and over.  How many franchises even remain from the PS1 generation?  That wasn't even that long ago, Nintendo has tons of franchises still left from the NES generation.  Why doesn't Sony build up Killzone like MS does gears of war?  This game costs much less to make, but gets much more sales than killzone. 

Call of Duty doesn't seem to have any trouble selling on PS3.  Why can't Sony hype up a game that is exclusive to PS3 that sells like Call of Duty?  MS has got FPS games on their system that sell more than Call of Duty.  The demographics are there.

edit: by games i mean game, although Gears is doing fine for itself as well.

yes the numbers are smaller, but if Halo can sell 11 million (more than 3 million more than COD4), then why can't a 1st party exclusive FPS on PS3 sell 7 million on PS3?  COD4 was able to sell 5 million on PS3, why is it that 3rd parties can tap the userbase better than Sony?

Exactly, a familiar brand that sells big numbers.  Something that Sony is lacking, which is my whole point.  Sony isn't the new guy on the block anymore but they don't have many big franchises to speak of.  They have a bunch of games that sell 1-2 million, but with today's costs that isn't enough profits anymore.  It's a big problem for Sony as they keep losing money each quarter.  There's nothing wrong with it as a gamer, but financially it's costing them big time.

@Johnsobas- Killzone exists to be Sony's huge exclusive shooter, so when they failed to properly advertise it much in the same way Microsoft does with Gears... it was confusing to me.
The game needed way more mainstream hype than it received.
Also, I think it needed to release Killzone 2 in the holiday season, the whole situation may have been carried out the way it was in order to build a first round of Killzone fans on the PS3. There were virtually no fans of the original Killzone, so 2 had to create an entire new following from practically nothing.
With Sony's rejuvenated sense of marketing since the Slim launch, one would hope that such an attitude would carry over until the release of Killzone 3, which could and should be the equivalent of Gears or Halo for Sony. They need to create a mega shooter franchise that is exclusive, because the fanbase IS there.
They need to release it in the prime time of a holiday season. If a COD is releasing in the same time, then Sony can try and avoid it by some time but they must not deviate from the Holiday season in favor of the following year.
SO
Sony must release Killzone 3 Holiday 2010, or wait all the way until Holiday 2011. They must go for the throat of all competition. Other games will re-schedule their launches around Killzone 3.
They need to spend 20 times the amount of marketing on Killzone 3, then they did on Killzone 2.

on another completely different topic; I expect the agent to get a LOT of publicity and be much much bugger than anyone expects. This game can and should co-exist during the same holiday release window as Killzone 3. Both games will do 4 million +
you heard it hear first!

If GT3 can sell 14 million why can't Forza 2 sell 5 million?

Have you ever considered that it's America that's in love with shooters, and X360 has almost double the amount of consoles sold in America as the PS3 does? Coupled that with rather poor advertising(until very recently), and of course their 1st party shooters aren't going to do that well. COD sells well because it isn't Sony advertising it, and it creates hype by itself simply through word of mouth. Simple as that.

If it's in 2010 then I'm sure it's going to be milk-a-thon. Once Cod3 came out you knew what was going to happen....
