It doesn't do soft body physics, no, only rigid body, but it absolutely has collision detection for smoke, or, as you said "real time smoke effects". Check the DX10 stalker alien video, when it blows the smoke all over the place. I've seen that happen in game. Also, throwing something through smoke will have it realistically interact, although it is not as pronounced as in Batman. I also very much doubt that Crysis is doing any, hower perfunctory, fluid dynamic simulations for its smoke effects, which the PhysX package clearly is (although incredibly mundane and simplistic).
