The ION Storm Daily Informant has a Deus Ex update (an actual update, not some weird X-Files website publicity stunt) from about the entire team, getting feedback from Designer Warren Spector, Lead Programmer Chris Norden, Design Team Leader Harvey "Witchboy" Smith, Design Team Leader Bob White, Programmer Scott Martin, Designer Steve Powers, Artist Russ Hughes, and Writer Sheldon Pacotti. Here's Scott Martin's update on progress on the game's AI, including the coveted sit in couch AI (now if only NPC's could operate the TV remote):

I'm still chugging along on the AI. I recently made some optimizations to decrease the AI's load on the CPU. Combat is getting more interesting as the NPCs get smarter. NPCs can now break glass, shoot through crates that enemies are hiding behind, react to loud noises (including footsteps), defend areas, run to alarms and trigger them to call reinforcements, sit in chairs or couches, and inconspicuously tail the player. And there's even more cool stuff on the way...
