HM beast tribes

[Alisi]

How do we gain access to the two new beast tribes? Have they been released or is this like the GC and it'll be in a future patch?

I've been google-fu-ing for a way to unlock them but I can't seem to find anything on those two. I did search the forums but all I'm getting (when I put in beast tribe) is ranting about gear, crafting, and discussions on hunts. Not terribly helpful.

Thanks! =^.^=

edit: the title of the thread is supposed to be HW, not HM. XD sorry!
