In a recent interview Michael Denny shared that Evolution Studios and Sony Liverpool are following under one management and looks to be fully merged into one development house.  It was also stated that the two have worked together on Motorstorm and are now sharing resources. In this you seem to get a sense of streamlining from Sony with their internal development studios. As you may or may not know Sony Online Entertainment now reports to Sony Computer Entertainment which is great when thinking about the type of content they can provide to the PlayStation platforms such as the upcoming Agency and DC Universe.
