To bad we won't se real benefits in a long term. PhysX was overhyped before and is still threaded like a stepchild in the industry today. There are some titles that excel on these effects and other implementations are just pure checkboxes to fullfill a contract it seems.
That new fluid physx looked cool, especially that jelly stuff - would be great in Ghostbusters I see its U4E standard now, next year there will be some really interesting U4E games no doubt
