Depends on which stuff you're talking about. I can say for what I know:
1. 3D weapons - 100% done. Though, it may need a slight improvements in the future.
2. 3D armors - about 70% done. Basic armors are ready, so the game without of 3D NPC's is possible already.
3. 3D misc. stuff - about 60% done.
4. Animations. Basic animations for characters are 85% done. But the game still require a specific animations, like holding stuff (with 1 and 2 hands), sitting, laying etc. The problem is that Karpov are absent for a month already, so nobody is making new animations.
Can't say for sure when all together will be ready to use, it's completely depends on people's free time and their will to do something.
