Tarantia Commons is currently planned to be in the same update cycle as the items and statistics update. (i.e. 1.05) It will certainly be on the public test servers during that cycle. Whether it launches in exactly the same update as the stats update will depend on testing. It may come at the same time, or it may come a little after (i.e. as a 1.05.x update just like we did with Ymir's Pass).
see the source.
I am looking foward to Tarantia commons and it has really captured my imagination.
I was afraid that FC pushed it further down the line, but no - it might hit the live servers in resonable ammount of time :D
