Deus Ex 2 is going to have a great physics-based sound system.
Fundamentally acoustics is all about physics. While the end effect has been mentioned, it's still unclear however just how in fact this Physics-based sound system is supposed to be implemented.
No doubt they'll still be using EAX for environmental acoustics, and I can only hope that they go full-bore on it.
