It's really pretty simple. Neither one of those games will be worth me shelling out $600 for a blueray player that also plays games. Lair, to me, is going to be hit or miss. Not everyone is into dragons. You're not going to get a bunch of casual gamers on that one. Same can be said with Warhawk. While both games may appeal to a good number of gamers out there, they wouldn't cause a member of the general public to go out there and spend $600 for a system, $60 for the game, and possibly $50 for another controller. Now if Sony had been able to secure something like GTA, a game that has already developed a huge fan base and is known pretty much around the world, then I could see someone plopping down that kind of cash specificly for the chance to play that game. System selling games are usually first party exclusive games that have become well known over the course of gaming history. Mario does it for Nintendo (along with Metroid, Zelda, and Smash Bros), Halo does it for Microsoft, but Sony has never really found a go to system seller. They might have something in God of War, but I'm sure that's at least a year or so away on the PS3. Gran Tourismo has gotten lamer with every sequel. GT4 was one of the worst. It was basically GT3.5. And unless their next entry is leaps and bounds better, it won't sell many PS3s either. Rachet & Clank are cute, and the gaming is brilliant, but they don't have the drawing power to sell systems either. Now, if MGS4 turns out to be a Sony exclusive (although there are several internet rumors to the opposite), then that might start selling systems. BUT, that is so far off, Sony might actually be far out of the race by then, and other companies might rethink their Sony exclusives (it's already happening), and start releasing the same titles on the 360 at the same time. It's really only good business for 3rd party companies to sell exclusively through a system if that system is doing well in sales. If, hypothetically, Sony was in 3rd place close to the time that MGS4 was preparing to release, Konami would have made a huge marketing mistake. But, if they saw a trend developing early enough to work their way out of any exclusiveness they may have granted Sony, then that would be another potential system seller gone.
Games that sell systems are few and far between. Games that sell $600 systems are nearly non-existant. I've yet to see one. And don't see any for '07. And that can be said for the 360 also. But their overall gaming experience, and XBL were the selling points for me. Why buy a game on the PS3 when you can buy the same thing on 360, and have the fun of working toward achievements and superior online support (try asking a NFS Carbon player on PS3 what I'm talking about). But, this isn't about which system is better, it's about system selling games. And right now, to me, only the Wii has 'em. And that's only because $250 is much easier for me to swallow than $400-$600.
Are you say that Warkhawk isn't a system seller to the PS3. The new Warhawk will have 40 players online and download stuff to the Playstation Store. You sound like an Xbox fanboy and alway will be.
