That makes sense to offer development solutions on all platforms, but what's interesting is Ageia's report that Xbox 360 can't handle all of the PhysX's features because of architecture limitations. PhysX offers technologies ranging from physical object interactions to fluid-based particle effects like water and smoke and reportedly only PS3 and PCs will be able to handle all the goods.
What will Xbox 360 miss out on? PhysX's fluid-based technology. How exactly that impacts Xbox 360's future is for all intents and purposes minimal, but it's strange to see a split between the two machines after such rabid debate over which one had the edge.
