For us developers it's of course also interesting to see the developer's tools. This is what I can see from the video:
- Autodesk 3ds Max 2009 SP1 for modelling
- Touchscreen and pen for modelling
- md6 format for models in the game (Quake3 used md3)
- Code looks like C or C++
- Data (e.g. animations) defined in a language which looks like JSON or also Ogre material scripts
- Perforce revision control system
