Should I be excited for Resistance 2? And other PS3 questions.

I mean, i recently got my PS3 (MGS4 <3) and i downloaded the demo of Resistance off the PSN and i wasn't really "wowed" by it. But then again, it's just a demo. I don't really feel like checking out the full game. Is Resistance 2 gonna be worth it with the new Socom coming out around the same time and Killzone won't be that far away as well.


and finally, what games should I check out for the PS3? I own:

MGS4
MLB 08: The Show
Uncharted
Rachet and Clank Future
Unreal Tournament 3
