They said that the Physics one wasn't in the cards, at least not yet. I suspect it will not materialise seeing as the Physics DLL is actually a DBPro wrapper for PhysX and TGC probably assume if we want it, we can always integrate directly with the Ageia SDK...
As for the AI, I would be curious to see it. I'm not interested on much of what's there, but I would like to see if the pathfinding requires "development-time waypoint creation" or it's a totally automated solution (that would look at an object you specify as a floorplan and figure out if you can walk there).
The AI thinggy, seeing as it is a complete TGC product is more likely to make its way to the GDK, if my marketing 101 knowledge is anything to go by....
I have vague plans for World Domination
