One of the things that will help them is the built-in support for PhysX cards in the Unreal Engine 3. The other thing that should help them is a die-shrink of the chip from 130nm to 80nm. This will reduce the power consumption and should make it possible to cut production costs.
As you probably remember, the first prototype boards featured physical support for both PCI and PCIe x1 slots, but in the end, only PCI models came to market, just like Killer-NIC and Creative's X-Fi. Where these three manufacturers missed the boat was the fact that number of PCI slots just kept on decreasing while PCIe cards were as rare as hen's teeth. With the PhysX card occupying the PCIe slot, the enthusiast market will be far more likley to implement Ageia's product in enthusiast computers.AGEIA is also working on a mobile version of their PhysX chip. This product will be installed in the ExpressCard slot of your notebook.
