I'm just glad my PTS character is lvl 12, just high enough to play in the WZ xD

, we've gotten most of that content already, and we seem to be getting updates about every month. 1.6 will bring us the WZ, so all that's really left is Makeb and the level cap. This year? Pushing it. But I can definitely see it coming late January, if not a bit sooner.
