It already does way more than TTS in the open beta. 
Even though not everything is in yet, it's practically done. You can check out 40-60 player semi-official community beta world hops on Sundays at 5pm if you're curious what's being done, there's some incredible shit being worked on. 
I think the holdup on the release is mostly just player voice system optimization, it gets janky with 40 players sometimes though it's fine with up to 20 and IK and voice are better than live with 5-15 in the same area.
