AGEIA has just acquired Meqon Research and a long time ago 3DRealms announced it had licensed Meqon for Duke Nukem Forever.
AGEIA is mentioning in the press release that Meqon's technology will be incorporated into the AGEIA PhysX SDK and as you've probably heard, BFG Technologies will soon release their AGEIA PhysX card (we're not sure about its overclocking potential though).
Of course, there is always the risk of these cards becoming obsolete until the game is out, but we never now, do we? Anyway, check the press release if you're interested.
