True, but only because of the logistics of it all. Who really wants to spend more money on another peice of hardware? Having to go back to the 3D accelerator days. But, if a common API is eventually chosen, and GPU's (which are more suited for the task) include the design needed, then I think it could be a good advancement.
I think nVidia buying Ageia, is the best thing that Ageia could have hoped for.
