It certainly looks interesting, and I look forward to hearing more about it.
That said, I would caution against getting too excited this early, as we barely know anything about it. All we have is some concept art, and a very general description of the basic idea. There are a lot of things we don't know, what sort of activities it will have, whether it will have a player house, or even whether it will be out in 6.0 (As opposed to having to wait for a later patch).
