Wow, almost every game you listed will not go to the PS3. They're published by MS.
MS is taking a publisher strategy to ensure exclusives instead of Sony's approach of buying developers and using their talents. Both have their advantages and disadvantages:
In a publisher model, you're constantly adapting to the environment and switching developers to go for the most bang-for-the-buck. In Sony's in-house model, you have the stability of a core developer, ownership of IP, but you're sacrificing mobility should a developer go downhill.
