A lot of posters seemingly forget that the 360 has a few critical advantages over the PS3. The first of those is the common architecture with the PC. The second is the higher attach rate not only for games proper, but for content packages. Third development for the 360 is cheaper and faster.
This is often reason enough for some developers to skip PS3 porting of games, or to decide not to deliver extra content that will probably not cover cost. Yes sometimes Microsoft money is involved, but honestly its not like the developers feel coerced into making this decision. Let alone that many developers make this decision with no money involved. Do any of us actually believe that Microsoft buys every exclusive that they get. A lot of it has to do with their positioning.
