Duh, we already had that. Don't you remember all the hype about the PS2's uparalleled Emotion-Engine? Yeah... neither did game developers.
Similarly, while the physics cards are neat for the new types of gameplay they could allow, I predict that even if they become common place, gameplay won't change. Developers will just use them so they can add another bullet-point to the back of the game box:
-Exploding crates splinter and fly through the air with realistic physics!
-Dead bodies flop around with "Rag-Doll Physics Mach 2" (tm)
or
-That guy's clothes move like they're real and stuff!
I only wish that developers (and publishers) would care more about substance than style.
