If you are a fan of Physx, you may like this - if Nvidia buys Ageia, PhysX is here to stay - regardless of consumers wanting it or not.

Presumably Nvidia intends to integrate a physics processing block into its GeForce line of graphics accelerators, possibly based on Ageia's work.Ofcourse, the attempted purchase could be a defensive move - to preclude Intel or anyone else from acquiring Ageia.

Personally, I think we are very far from being physics limited in games, so the benefits, if any, of such an acquisition would be years down the line.
