A playable one is still under progress, since every bit of content has to be recreated, so it takes some time and for now i think there's only the test server publicly accessible.
The main thing, is that we are not that many people with the knowledge to work on it and we do it when we can find time, but still, there is progress, even though not everything is visible to the public.
I think you might want to give it some time, and revisit the site from time to time, maybe some day we'll have a playable server, we all hope so atleast.
