There is no question that the PS3 will be getting the better share of the ESTABLISHED games this year, however even in this area Sony's advantage over the 360 is not as vast as many claim.

However, many people are rountinely claiming that the PS3 will have more AAA games than the 360 this year, and I thought I'd do an examination of the likelihood this will actually happen. I define a AAA title as one that has an average score OVER 90%

To help make this comparison, I will be using gamerankings.com and the thread at the bottom of the page (I trust ssj12 is a big enough Sony fan to put every game I need to consider for the PS3 in that thread), as well as my own knowledge.

What follows is a list of the past few titles and their scores (or only one if available) in each PS3 series releasing THIS year. I will not include multiplatform titles or timed exclusives unless there is a reasonable chance that the other console's version WONT launch thisyear.

PS3:

Killzone 2: Killzone 1 scored 73.5 NOT AAA

Singstar: Majority of titles under 80%, PS3 version released in Europe and at 82.5%. NOT AAA

Metal Gear Solid 4: Majority of main PSX and PS2 titles over 90%, LIKELY AAA

Gran Turismo 5: Last title wasn't AAA, however most have been. Probably WONT be out this year. Likely AAA

Final Fantasy XIII: Probably WONT be out this year, the majority of titles are around 90%. Likely AAA

Tekken 6: Inconsistent history, last two titles have MISSED AAA status. POSSIBLE AAA

Resistance 2: Last title NOT AAA, however great developers and expense spared on sequel. POSSIBLE AAA

Motorstorm 2: Last title scored 82.3. NOT AAA

SOCOM: Confrontation: No home console has EVER made AAA status. NOT AAA

Total likely AAA titles: 3

Total possible AAA titles: 2

Sony has LBP and Haze that are unproven titles that may go AAA with big budgets, hype and talent.

Two of Sony's likely AAA titles may not make 2008.

XBOX 360:

Halo Wars: Every title easily AAA, however this game is produced by different studio. Possible AAA

Fable 2: Last title received 85.2 on gamerankings. NOT AAA

Gears of War 2: Last title received 93.8. Likely AAA

Forza Motorsport 3: Last titles at 92.9% and 89.8%. Maybe not in 2008. Likely AAA

Splinter Cell: Conviction: Many titles, the majority on Xbox over 90%. Most recent just under. Likely AAA

Ninja Gaiden 2: Both Xbox titles were easily AAA. Likely AAA

Banjo-Kazooie 3: Both previous console titles were AAA. Likely AAA

Viva Pinata 2: Former title was 84.9 on gamerankings. NOT AAA

Total likely AAA titles: 5

Total possible AAA titles: 1

Microsoft has a clear advantage in new IP this year with Too Human, Alan Wake and Lost Odyssey, with general consensus being they have more unannounced games than Sony (IMO). However despite recent rumours to the contrary, I remain doubtful that FM3 will make 2008

From this list, drawn from an unbiased statistics gathering website, we can see that whilst Sony may have many high-profilegames that are easy to market, the Xbox 360 has a far greater chance of a large number of AAA games than the PS3.

Edit: It is also worth noting that most multi-platform games that were already released that I encountered has a better score on the Xbox 360 than on the PS3.

Banjo-Kazooie 3 likely? Bwahahahahaha, not blutay likaly!

Why do you say that Aj? Both of it's previous console titles were AAA. To say that Banjo isn't likely to be AAA, would be like saying FFXIII probably wont be AAA just because a couple of FF's didn't make 90%.

Rare has said remarkably little about Banjo-Threeie at this point so it’s really hard to tell one way or the other at this point.  However, I’ve heard that Rare’s Banjo team is relatively intact since the N64 days and given the previous titles that bodes well for quality.  And while we haven’t heard much yet I expect Microsoft to heavily promote it as yet another to break into the family market.  They won’t succeed with that but I expect Banjo to be good anyway.

Then again Microsoft still hasn’t said much about its exclusives this year yet at all.  So I agree that the PS3 definitely has plenty of more established franchises and it’s quite hard to tell at this point whether the 360’s exclusives will hit or miss.  I do expect them to wind up with plenty of great games this year…definitely more than a lot of people seem to be giving them credit for.  

Motorstorm not AAA... you fail. This generation 80%+ is AAA.

Also you missed GT5: Prologue. It is a full game after all.

I'd say PC wins =D

I love how you say the 360 has "the clear advantage" in new IPs when 1. -they're new IPs, so they could flop like Lair, and 2. -you leave off a bunch of the ps3's new IPs, like White Knight Story and inFamous.

Edit: And unannounced games like Gears of War 2 and Forza 3 are as likely to come out in '08 as God of War 3. This list is extremely biased.

 The funny thing is that we actually know for afact that God of war 3 is in production as stated by the last to directors of GoW games.

Gears 2 is speculation but would be obviouse that its been in production as cliffy b hasen't made a siting since last E3.

Forza 3 just aint gunna happen no matter what rumors say especially now that PGR devlopers are under activision blizzard 

Gears 2 probably isnt coming out till 2009 anyways.
