From this point on, Sony's first and second party is just pumping out the titles.
We just got LittleBigPlanet and MotorStorm 2. Resistance 2 is next week. Killzone 2 is hitting February (and it will OWN - trust me), and White Knight Chronicles should hit the West around that time. InFamous will follow in May. Ratchet & Clank Future 2 and Uncharted 2 are a lock for the end of the year, despite having not been announced yet, and God of War 3 should make it out by then as well.
