The future of PhysX according to NVidia

Feb 13, NVidia purchased Ageia, the company that developed the PhysX, a rendering graphics engine (to model physics interactions) used in some games via an additional daughterboard.
NVidia has indicated what the future of PhysX will be. The daughter-cards will be abandoned. The physics engine will be managed in the future by some GeForce chips, perhaps the current 8800.
Bad news, however. It will be at least two cards (so nothing really changes) which will significantly push up the bill.
It is likely that in the future, the next generation of cards will have enough power to handle 3D renderings and physical interations at the same time.
