The ramifications of this subdued announcement are actually quite significant. Three titles have been revealed to have used the PhyreEngine for development: flOw, GripShift and DiRT. Of those three, only one is exclusive to PlayStation. It appears that the PhyreEngine is truly cross platform -- Sony is indirectly contributing to the development of PC and Xbox 360 games.
But why make it easier to make games on a competing console? Well, it's undeniable that developers are increasingly focused on multiplatform development. It's been rather commonplace for developers to neglect PS3 with inferior and oftentimes delayed versions of multiplatform games. With PhyreEngine, Sony is making a much more attractive plea: make games on PS3 first, guaranteeing high quality games that will not only match their 360 counterparts, but in many cases can exceed them. Sony's message is clear: start games on the PS3, and they will be better for both PS3 and 360 owners. It appears to us that PhyreEngine is a crucial part of that plan.
More details of PhyreEngine will undoubtedly be unveiled later today at a GDC dedicated to what Sony has dubbed "the new hotness." Stay tuned.
