From what I've heard, I do believe we will be setting up a Tanoa server.
Remember, Tanoa hasn't even been released yet, and even after it is there would need to be a ton of scripting and modifying to give it whatever purpose it's been assigned (I&A, Wasteland, Tanoa Life, etc.) Meaning if we do have a Tanoa server, it wouldn't be out for quite a while.
But I haven't heard this officially, just from rumors, so I wouldn't count on it.
