Let's make a little study if you want post with your choice:

1- You own a PS3 and would buy one of those games

2- You own a PS3 but you aren't interested in any of those games

3- You don't own a PS3 but you definitely buy one to play one of those games no matter what

4- You don't own a PS3, you are interested in any of those games but you'll wait and see if you would buy a PS3 to play the game

5- You don't have a PS3 but you would buy one regardless any of those games

6- You won't have a PS3 never

It's not the better research we could, but as a gamming community we can try and extrapolate interesting results from this study :P.

Feel free to modify the questions, and if you agree I can count tomorrow and post, what do you guys think?

I think Sony fans are putting too much weight on these titles. They will be big, important titles for the PS3 but none of these scream 'saviour' to me. Specifically:

Killzone 2: I feel this game is WAY overhyped, like the original. I fear they have now obligated themselves to spend so much time on the graphics that gamepaly will only be average, much like the original. This will sell well, but nothing that will create momentum.

FFXIII: The FF series peaked at VII. This will sell very well, especially in Japan and this, White Knight and MGS4 may give the PS3 much needed life in Japan, and to a lesser extent Europe, but won't be able to overcome the momentum of the 360 in America.

MGS4: What's the most MGS has ever sold? Really? Again this will be strong, but to think it can make the difference is just kidding yourself.

Now GTA exclusive, that'd have been huge. But with the extra downloadable content the 360 version will appear superior.

End of the day, I think these games will help the PS3 get a larger lead in Japan and Europe over the 360, but they'll never take back NA this generation. PS3 may pass the 360 but it'll be near the end of this cycle, much like how the Xbox overtook the GC.

Well considering that the 360 sold more software even on the week of the launch of Mario Galaxy,also a week in which they sold 256k units of harware, I do think the 360 will continue to sell more software. This week was their best opportunity to sell the most software for a given week.

The Wii is a year old. How much software did the 360 push year one?

13 million+ which is 7 million more then the competition. (Splinter Cell) This accounts for all MGS and SC games.

When you need to know what Sony needs to turn things around you need to know what there up against.

MS has Fable 2 (Fable 2.6 million ) against FFXIII (FFXII 4.95 million)

Lets not forget the granddaddy of all racing games, Gran Turismo 5. GT can sell a guaranteed 6 million units.

Although these numbers don't give anyone the reason to say that they are system sellers (except for GT) These games, compared to the competition, sell more. The PS2 market will see that these high profile games will never hit the 360. Some won't care, but the ones who do care will buy a PS3. That will be a large chunk of former PS2 owners.  

Dont forget that the PS2 had a much larger installed base than the original xbox. putting FF 12 sales on Fable or xbox splinter cell on PS2 mgs isnt reasonable for that matter. Remeber, even ratchet sold 3-4 million on each iteration on the PS2 but it doesnt seem to be pushing the ps3 hardware too much

 What the hell did you just say?

And the reason was? Metal Gear Solid 2, Gran Turismo 3, and Final Fantasy X. Final Fantasy X sold nearly 8 million units. And all three came out within Sony's PS2 first and early second year. While Fable came late in the last generation ( a year + before 360 launch). I compared those numbers (FFXII and Fable) because they were within the same timeframe.

Im sure if the xbox had sold 80 million units of hardware also, the Fable numbers would have been at least slightly higher. Your retarded if you dont believe that

 Okay MGS, and MGS2 sold about 6m each, MGS3 less than 4m.  Not bad at all, but compared to the up to 15m GTA or Mario or FF games sale, it's not much at all. Certainly not enough to save a 3rd place system.  If Nintendo's games like Mario Kart, SSBM and SMS couldn't save the GC dispite selling about 6m each, what chance does a game like MGS have to do so for a third place system? In Japan, maybe. NA - no way. MGS4 will be very lucky to hit 2m lifetime IMO. Unless it goes to... oh no I'm not starting that debate again.
