I will have to fully agree with Superchunk on this one. A lot of people on this chat forum do not understand why the PS3 is not selling like crazy. Its game don't appeal to anyone but to the hardcore--a niche group that's a dying breed (heavy-violence and lack of positive intelligence that doesn't solve anything; aka GTA). Of course the casuals, over time, will become a better and new form of this emo-hardcore group we have now that is more centric and bent on having fun rather than bleeding your eyes into an orgasm while your brain goes dead.
Besides, does the new gaming community need the same experience rather than giving something new? I'd say that Nintendo got it right and people love 'change.'
Besides, Superchunk, the ONLY console that benefited on the release of GTAIV was NOT the PS3 or X360. It was the Wii with nearly 1 million units sold on the release week of GTAIV, and that games not available on the Wii. I think that when MGS4 is released, the Wii will go past 500k units sold. I bet Nintendo is holding back on their Wii consoles when the competition is releasing a heavy-hitter game title.
EDIT: Oh, and to be on topic, I think the only games that would save the PS3 are the ones that appeal to the mass-market and not something that will turn people off. Something that's easy to play and understand. I don't think Sony has anything like that in their arsenal. When I look on IGN for their games list on releasement, they are games that I don't think any family would want to own. They need something family-oriented. BADLY...otherwise I don't think their system can try to bring back marketshare or fanbase.
