An interesting development has reared its head into the exclusivity debate, with the signing of a "perpetual licensing agreement" that will make the Havok physics engines available to Microsoft Game Studios and its development partners. With such a close relationship forming, will we see Sony and Microsoft become seperated with exclusivity, not between game titles, but the actual engines they use? Could it be that future titles on the 360 will have the latest physics engine and those on Sony will not?
