I have always believed than on a near future (2 years) the whole purpose of a PPU was to create a realistic model that would work all the time. For example, instead of using static volumetric effects for fog and such it could be all dynamic particles that would be affected by wind and passing objects including bullets. Water would be like in the fluids demo (all particles again) and basically every model would be made of particles, or at least be taken as particles for physics calculation as in cloth and deformable models.
Aditionally I think physics cards could be used for some photon based lighting effects, such as Ambient Oclusion or Global Ilumination models.
The list of things that a PPU could do with close to 100% usage is long. Game developers just have to start using them, but of course they will have to do it step by step.
