I think exclusive games will do the trick for the PS3. Even if many are sequels, lets not forget that UC2 was also a sequel, so was God of war 3.
Sequels can sell systems as well, sometimes more than new IPs which are usually not even popular.
And the last guardian is a good new IP as well. And there will definitely be more PS games announced later on for the move. We have right now 2 games both announced last year.
A system doesn't have to sell to a different audience to sell more. Also, if the casual want a casual experience, its highly doubtful that they will go out and buy a more expensive option of kinect compared to the wii. And wii has more games than kinect as well.
But either way, I won't be disappointed. Sony is doing what they can, and I am happy for it.
